-4=1-sqrt(x^2-11)

- 4 = 1 - x^{2} - 11

x = 6, x = - 6

Solution steps

- 4 = 1 - x^{2} - 11

Move

x^{2} - 11

to the left side

- 4 + x^{2} - 11 = 1

Move

4

to the right side

x^{2} - 11 = 5

Square both sides:

x^{2} - 11 = 25

x^{2} - 11 = 25

Solve

x^{2} - 11 = 25 : x = 6, x = - 6

x = 6, x = - 6

Verify Solutions:

x = 6

True

, x = - 6

True

The solutions are

x = 6, x = - 6

9 = 5 x - 4

2 x - 5 - 2 x = 0

2 (x + 15) - 3 = x

3 x^{\frac{3}{4}} = 24

x^{2} + x = 0
