Introduction
Quadratic functions are a fundamental concept in mathematics, and understanding how to convert them from factored form to standard form is crucial for solving various mathematical problems. In this article, we will explore the process of matching quadratic functions given in factored form with their equivalent standard form.
What are Quadratic Functions?
Quadratic functions are polynomial functions of degree two, which means the highest power of the variable (usually x) is two. They can be represented in two forms: factored form and standard form. The factored form of a quadratic function is expressed as a product of two binomials, while the standard form is expressed as a single polynomial.
Factored Form to Standard Form
To convert a quadratic function from factored form to standard form, we need to multiply the two binomials. This can be done using the distributive property, which states that a(b + c) = ab + ac.
Example 1: Converting Factored Form to Standard Form
Let's consider the quadratic function f(x) = (x + 3)(x - 4). To convert it to standard form, we need to multiply the two binomials:
f(x) = (x + 3)(x - 4) = x(x - 4) + 3(x - 4) = x^2 - 4x + 3x - 12 = x^2 - x - 12
Example 2: Converting Factored Form to Standard Form
Now, let's consider the quadratic function f(x) = (x - 2)(x + 6). To convert it to standard form, we need to multiply the two binomials:
f(x) = (x - 2)(x + 6) = x(x + 6) - 2(x + 6) = x^2 + 6x - 2x - 12 = x^2 + 4x - 12
Example 3: Converting Factored Form to Standard Form
Let's consider the quadratic function f(x) = (x + 2)(x - 3). To convert it to standard form, we need to multiply the two binomials:
f(x) = (x + 2)(x - 3) = x(x - 3) + 2(x - 3) = x^2 - 3x + 2x - 6 = x^2 - x - 6
Example 4: Converting Factored Form to Standard Form
Now, let's consider the quadratic function f(x) = (x - 1)(x + 12). To convert it to standard form, we need to multiply the two binomials:
f(x) = (x - 1)(x + 12) = x(x + 12) - 1(x + 12) = x^2 + 12x - x - 12 = x^2 + 11x - 12
Matching Quadratic Functions
Now that we have converted the quadratic functions from factored form to standard form, let's match them with the equivalent standard form listed on the left.
A.
To match this quadratic function, we need to find the factored form that corresponds to it. Let's consider the factored forms listed above and multiply them to see which one matches:
- (x + 3)(x - 4) = x^2 - 4x + 3x - 12 = x^2 - x - 12 (does not match)
- (x - 2)(x + 6) = x^2 + 6x - 2x - 12 = x^2 + 4x - 12 (does not match)
- (x + 2)(x - 3) = x^2 - 3x + 2x - 6 = x^2 - x - 6 (does not match)
- (x - 1)(x + 12) = x^2 + 12x - x - 12 = x^2 + 11x - 12 (matches)
Therefore, the factored form of the quadratic function f(x) = x^2 - 11x - 12 is (x - 1)(x + 12).
B.
To match this quadratic function, we need to find the factored form that corresponds to it. Let's consider the factored forms listed above and multiply them to see which one matches:
- (x + 3)(x - 4) = x^2 - 4x + 3x - 12 = x^2 - x - 12 (does not match)
- (x - 2)(x + 6) = x^2 + 6x - 2x - 12 = x^2 + 4x - 12 (does not match)
- (x + 2)(x - 3) = x^2 - 3x + 2x - 6 = x^2 - x - 6 (does not match)
- (x - 1)(x + 12) = x^2 + 12x - x - 12 = x^2 + 11x - 12 (does not match)
However, we can try to factor the quadratic function f(x) = x^2 - 4x - 12 as (x - 6)(x + 2).
C.
To match this quadratic function, we need to find the factored form that corresponds to it. Let's consider the factored forms listed above and multiply them to see which one matches:
- (x + 3)(x - 4) = x^2 - 4x + 3x - 12 = x^2 - x - 12 (does not match)
- (x - 2)(x + 6) = x^2 + 6x - 2x - 12 = x^2 + 4x - 12 (does not match)
- (x + 2)(x - 3) = x^2 - 3x + 2x - 6 = x^2 - x - 6 (does not match)
- (x - 1)(x + 12) = x^2 + 12x - x - 12 = x^2 + 11x - 12 (does not match)
However, we can try to factor the quadratic function f(x) = x^2 + x - 12 as (x + 4)(x - 3).
D.
To match this quadratic function, we need to find the factored form that corresponds to it. Let's consider the factored forms listed above and multiply them to see which one matches:
- (x + 3)(x - 4) = x^2 - 4x + 3x - 12 = x^2 - x - 12 (matches)
Therefore, the factored form of the quadratic function f(x) = x^2 - x - 12 is (x + 3)(x - 4).
