Answer 1

no solution

no solution

Explanation:

To solve radical equations, you need to isolate the square root and square both sides. Then at the end, you must check solutions for extraneous solutions.

10.

`√(5x - 10) + 6 = 4`

`√(5x - 10) = -2`

A square root is always a non-negative number. Since the square root on the left equals -2, there is no real solution.

11.

`√(2x^2 + 8x - 4) + 6 = 5`

`√(2x^2 + 8x - 4) = -1`

A square root is always a non-negative number. Since the square root on the left equals -2, there is no real solution.
