sqrt(1-x)+sqrt(x+9)=4

1 - x + x + 9 = 4

x = 0, x = - 8

Solution steps

1 - x + x + 9 = 4

Remove square roots

4 x^{2} + 96 x + 576 = 64 x + 576

Solve

4 x^{2} + 96 x + 576 = 64 x + 576 : x = 0, x = - 8

x = 0, x = - 8

Verify Solutions:

x = 0

True

, x = - 8

True

The solutions are

x = 0, x = - 8

x - 2 + 4 = x

8 x - 2 x + 2 = 7

4 x - 6 = x + 9

x = - 5

5 - q = q + 7
