Question

Harry solved a quadratic equation. His work is shown below. In which step did Harry make an error? (x-5)^2+6=42

Answer 1

X = 11, - 1

Explanation:

Given (x-5)^2 +6 = 42

Subtract 6 from sides

(x-5)^2 = 36

take the square root of both sides

X - 5 = +/- 6

X = 11, - 1.

Harry did not solve for X.
