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?
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]
