Introduction

In algebra, a perfect square trinomial is a quadratic expression that can be factored into the square of a binomial. It has the form $(a+b)^2$ or $(a-b)^2$, where $a$ and $b$ are constants. In this article, we will learn how to calculate the number that needs to be added to each side of the equation $w^2 - 3w = 350$ to create a perfect square trinomial.

Understanding Perfect Square Trinomials

A perfect square trinomial is a quadratic expression that can be written in the form $(a+b)^2$ or $(a-b)^2$. It has the following properties:

• It is a quadratic expression that can be factored into the square of a binomial.
• It has the form $(a+b)^2$ or $(a-b)^2$, where $a$ and $b$ are constants.
• It can be written in the form $a^2 + 2ab + b^2$ or $a^2 - 2ab + b^2$.

Step 1: Rearrange the Equation

To create a perfect square trinomial, we need to rearrange the equation $w^2 - 3w = 350$ to the form $w^2 - 3w + c = 350$. We can do this by adding a constant $c$ to both sides of the equation.

w^2 - 3w = 350
w^2 - 3w + c = 350 + c

Step 2: Find the Value of c

To find the value of $c$, we need to complete the square. We can do this by adding $(\frac{-3}{2})^2 = \frac{9}{4}$ to both sides of the equation.

w^2 - 3w + \frac{9}{4} = 350 + \frac{9}{4}

Step 3: Simplify the Equation

We can simplify the equation by combining the constants on the right-hand side.

w^2 - 3w + \frac{9}{4} = \frac{1400 + 9}{4}
w^2 - 3w + \frac{9}{4} = \frac{1409}{4}

Step 4: Write the Equation in the Form of a Perfect Square Trinomial

We can write the equation in the form of a perfect square trinomial by factoring the left-hand side.

(w - \frac{3}{2})^2 = \frac{1409}{4}

Conclusion

In this article, we learned how to calculate the number that needs to be added to each side of the equation $w^2 - 3w = 350$ to create a perfect square trinomial. We rearranged the equation to the form $w^2 - 3w + c = 350$, found the value of $c$ by completing the square, simplified the equation, and wrote it in the form of a perfect square trinomial.

Final Answer

The number that needs to be added to each side of the equation $w^2 - 3w = 350$ to create a perfect square trinomial is $\frac{9}{4}$.
