sqrt(20-x^2)+x+2=0

20 - x^{2} + x + 2 = 0

x = - 4

Solution steps

20 - x^{2} + x + 2 = 0

Remove square roots

20 - x^{2} = x^{2} + 4 x + 4

Solve

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

x = 2, x = - 4

Verify Solutions:

x = 2

False

, x = - 4

True

The solution is

x = - 4

y = y - 1

8 x + 2 = 10

\frac{x ( x - 6 ) ^{2}}{3} = 0

2 x + 21 - 2 = 1

x - 3 = 5 x + 5
