Rewrite the function by completing the square. f(x)=x^2+x-30 it’s supposed to look like this f(x)= (x+ )^2+ .

Step-by-step explanation:

In this question we are required to rewrite the given function by using completing the square method.

Completing the square method requires that our given equation can be written in form:

SO, we have to transform our equation according to above format.

Since our equation is , we will transform it into

because the middle term of given equation has + sign.

We have introduced (1/2)^2 on both sides of the equation to gain the required form.

Our answer is

linear pair postulates

2 over 5 and 4 over 15

don’t know last one sorry
