Question

Which of the following correctly isolates the constant for the polynomial: x^2 - 12x + 27

A. x^2 - 12x= -27
B. x^2 - 12x= 27
C. x^2 +27= 12x
D. x^2 - 12x = 36

Answer 1

Hmm...

x^2 - 12x = -27

^ This is the correct answer because...if you want to bring anything to the opposite side of the equal sign (=) it also changes to its opposite. For example: 27, also known as +27 would change into a -27. Therefore, the answer is A. :)
