sqrt(x^2+5x+20)=4

x^{2} + 5 x + 20 = 4

x = - 1, x = - 4

Solution steps

x^{2} + 5 x + 20 = 4

Square both sides:

x^{2} + 5 x + 20 = 16

x^{2} + 5 x + 20 = 16

Solve

x^{2} + 5 x + 20 = 16 : x = - 1, x = - 4

x = - 1, x = - 4

Verify Solutions:

x = - 1

True

, x = - 4

True

The solutions are

x = - 1, x = - 4

2 x - 7 = 13

3 x = 5 x + 4 - 2

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

y, x = - y^{2}

2 x^{2} - 4 = x
