Answer:

A.x(x+12) -7(x+12)

Step-by-step explanation:

Factoring is the process of taking common terms out of an expression such that one can represent the expression as the result of smaller values. When given the following expression:

x^2 +5x - 84

First, represent the linear term as the sum of two terms such that each term shares a common factor with the other terms in the expression.

x^2 +12x - 7x - 84

Now take out the common factors,

x(x+12) -7(x+12)

Thus, the correct option is choice (A).

What are the roots of the quadratic function in the graph?<br> -15<br> -5,3<br> -5,-3<br> -3,5
nasty-shy [4]

Answer:

-5 and 3

Step-by-step explanation:

The roots of a quadratic function are also called the x intercepts.

The x intercepts are found by looking where where the quadratic equation crosses the x, or horizontal axis.

In this case, the quadratic equation crosses the x axis at (-5,0) and (3,0).

Therefore, our roots are -5 and 3
