Question

1. How many solutions does the equation ( − ) − = have?

Answer 1

2 → 15; -1

Explanation:

1. -

`(x-7)^(2) - 27 = 37\\(x-7^(2) = 37 + 27\\(x-7)^(2) = 64\\x-7 = √(64) \\x - 7= \sqrt{8^(2)}\\ x = 8 + 7\\x = 15`

2. -

`x-7)^(2) - 27 = 37\\(x-7^(2) = 37 + 27\\(x-7)^(2) = 64\\x-7 = -√(64) \\x - 7= -\sqrt{8^(2)}\\ x = -8 + 7\\x = -1`

Hope it helped,
