2=sqrt(x^2+x-2)

2 = x^{2} + x - 2

x = 2, x = - 3

Solution steps

2 = x^{2} + x - 2

Square both sides:

4 = x^{2} + x - 2

4 = x^{2} + x - 2

Solve

4 = x^{2} + x - 2 : x = 2, x = - 3

x = 2, x = - 3

Verify Solutions:

x = 2

True

, x = - 3

True

The solutions are

x = 2, x = - 3

4 - 4 - 7 n = - 5 - 2 n

9 x^{2} = 2 x + 1

x + 6 = 25 x

x + 5 + 7 = 10

a^{2} = a
