Randy Kane · Answer 1

The values are just 3 and - 1/2 and that is all

Selina Molina · Answer 2

To solve an equation with a square yo would take the square root of both sides.

(4x - 5) ^2 = 49

sqrt ((4x - 5) ^2) = sqrt49

4x - 5 = + - 7

4x - 5 = 7 and 4x - 5 = - 7

4x = 12 4x = - 2

x = 3 x = - 1/2
