Question

Solve quadratic equations (x-15)² = 36

Answer 1

x = 21

Explanation:

(x-15)² = 36

The first step in solving this would be to take the square root from both sides which is this thing:
`√(x)`

now the 2 gets canceled out

`√(36)` = 6

x-15 = 6

add 15 on both sides to get x by itself

x = 21
