12(x^2-x-1)+13(x^2-x-1)=25(x^2-x-1) what does x equal?

x = any real number

Step-by-step explanation:

12(x^2-x-1)+13(x^2-x-1)=25(x^2-x-1)

Combine like terms on the left side

The items inside the parentheses are identical so

25 (x^2-x-1) = 25 (x^2-x-1)

Subtract 25(x^2-x-1) from each side

25 (x^2-x-1)-  25 (x^2-x-1)= 25 (x^2-x-1)- 25 (x^2-x-1)

0=0

This is always true, so x can be any real number
