sqrt(x+3)=x+3

x + 3 = x + 3

x = - 2, x = - 3

Solution steps

x + 3 = x + 3

Square both sides:

x + 3 = x^{2} + 6 x + 9

x + 3 = x^{2} + 6 x + 9

Solve

x + 3 = x^{2} + 6 x + 9 : x = - 2, x = - 3

x = - 2, x = - 3

Verify Solutions:

x = - 2

True

, x = - 3

True

The solutions are

x = - 2, x = - 3

10 = (- 3 - 5)^{2} + (6 - y)^{2}

x^{2} + 2 - x = 2

6 x^{2} - x - 6 = 0

1.5 = 2.18 (1.55 - x)^{\frac{3}{2}}

2.5 = 2 π \frac{l}{3.711}
