hello! I’m very confused on this question, I want to know if my format is good? I currently have x^2-14x=16 Am I on the right track?

#2**0 **

Solve for x:

1/2 (x^2 - 14 x) = 16

Multiply both sides by 2:

x^2 - 14 x = 32

Add 49 to both sides:

x^2 - 14 x + 49 = 81

Write the left hand side as a square:

(x - 7)^2 = 81

Take the square root of both sides:

x - 7 = 9 or x - 7 = -9

Add 7 to both sides:

x = 16 or x - 7 = -9

Add 7 to both sides:

** x = 16 ** or x = -2 [Throw this one out]
