Answer 1

Complete the equivalent equation for –7x – 60 = x2 + 10x.

( x + 5 )( x + 12 ) = 0

What are the solutions of –7x – 60 = x2 + 10x?

x = -12 or -5

Answer 2

(x+12)(x+5)=0

Explanation:

Complete the equation you must first write the equation in standard form ax^2+bx+c.

This means -7x - 60 = x2 + 10x becomes x2 +17x + 60=0.

Now that it is in standard form, you can factor the equation.

It factors into two numbers which multiply to 60 and add to 17. The numbers are 12 and 5.

So the factors are (x+12)(x+5) =0.
