Simplify The Expression: $ -50x^2 + 10x - 100 $
Understanding the Expression
The given expression is a quadratic expression in the form of $ ax^2 + bx + c $, where $ a = -50 $, $ b = 10 $, and $ c = -100 $. To simplify this expression, we need to factorize it, if possible, or use other algebraic techniques to rewrite it in a simpler form.
Factoring the Expression
One way to simplify the expression is to factorize it. However, in this case, the expression does not seem to be factorable easily. We can try to factor out the greatest common factor (GCF) of the terms.
Finding the Greatest Common Factor (GCF)
To find the GCF of the terms, we need to identify the common factors of the coefficients and the variables. In this case, the coefficients are $ -50 $, $ 10 $, and $ -100 $, and the variables are $ x^2 $, $ x $, and the constant term.
-50x^2 + 10x - 100
The GCF of the coefficients is $ -10 $, and the GCF of the variables is $ x^2 $. Therefore, we can factor out $ -10x^2 $ from the expression.
-10x^2(5 - x/5) - 10(10)
However, this is not a simplified form of the expression. We can try to simplify it further by combining the like terms.
Combining Like Terms
We can combine the like terms in the expression by adding or subtracting the coefficients of the same variables.
-10x^2(5 - x/5) - 100
However, this expression is still not simplified. We can try to simplify it further by rewriting it in a different form.
Rewriting the Expression
We can rewrite the expression in a different form by using the distributive property of multiplication over addition.
-50x^2 + 10x - 100 = -50x^2 + 10x - 100 + 0
However, this expression is still not simplified. We can try to simplify it further by using other algebraic techniques.
Using Other Algebraic Techniques
We can use other algebraic techniques, such as completing the square or using the quadratic formula, to simplify the expression.
Completing the Square
To complete the square, we need to rewrite the expression in the form of $ a(x - h)^2 + k $, where $ a $, $ h $, and $ k $ are constants.
-50x^2 + 10x - 100 = -50(x^2 - 1/5x) - 100
However, this expression is still not simplified. We can try to simplify it further by completing the square.
-50(x^2 - 1/5x) - 100 = -50(x^2 - 1/5x + 1/100) - 100 + 50/100
Simplifying the expression further, we get:
-50(x^2 - 1/5x + 1/100) - 100 + 50/100 = -50(x - 1/10)^2 - 50 + 50/100
However, this expression is still not simplified. We can try to simplify it further by rewriting it in a different form.
Rewriting the Expression
We can rewrite the expression in a different form by using the distributive property of multiplication over addition.
-50(x - 1/10)^2 - 50 + 50/100 = -50(x - 1/10)^2 - 50 + 1/2
However, this expression is still not simplified. We can try to simplify it further by using other algebraic techniques.
Using the Quadratic Formula
We can use the quadratic formula to simplify the expression.
-50x^2 + 10x - 100 = -50(x^2 - 1/5x) - 100
However, this expression is still not simplified. We can try to simplify it further by using the quadratic formula.
x = (-b ± √(b^2 - 4ac)) / 2a
In this case, $ a = -50 $, $ b = 10 $, and $ c = -100 $. Plugging these values into the quadratic formula, we get:
x = (-(10) ± √((10)^2 - 4(-50)(-100))) / 2(-50)
Simplifying the expression further, we get:
x = (-10 ± √(100 - 20000)) / (-100)
However, this expression is still not simplified. We can try to simplify it further by rewriting it in a different form.
Rewriting the Expression
We can rewrite the expression in a different form by using the distributive property of multiplication over addition.
x = (-10 ± √(-19900)) / (-100)
However, this expression is still not simplified. We can try to simplify it further by using other algebraic techniques.
