5=sqrt(3^2+x^2)

5 = 3^{2} + x^{2}

x = 4, x = - 4

Solution steps

5 = 3^{2} + x^{2}

Square both sides:

25 = 9 + x^{2}

25 = 9 + x^{2}

Solve

25 = 9 + x^{2} : x = 4, x = - 4

x = 4, x = - 4

Verify Solutions:

x = 4

True

, x = - 4

True

The solutions are

x = 4, x = - 4

2 x + 8 = x + 4

6 + 4 x - 12 = x

8 x = 4 x

5 x - 2 x - 2 = 0

(x^{2} - 5 x - 28)^{\frac{4}{3}} = 16
