G(x)=3sqrt(x+8)

G (x) = 3 x + 8

x = \frac{9 + 3 9 + 32 G ^{2}}{2 G ^{2}}, x = \frac{9 - 3 9 + 32 G ^{2}}{2 G ^{2}}

Solution steps

G (x) = 3 x + 8

Square both sides:

G^{2} x^{2} = 9 x + 72

G^{2} x^{2} = 9 x + 72

Solve

G^{2} x^{2} = 9 x + 72 : x = \frac{9 + 3 9 + 32 G ^{2}}{2 G ^{2}}, x = \frac{9 - 3 9 + 32 G ^{2}}{2 G ^{2}}

x = \frac{9 + 3 9 + 32 G ^{2}}{2 G ^{2}}, x = \frac{9 - 3 9 + 32 G ^{2}}{2 G ^{2}}

Verify Solutions:

x = \frac{9 + 3 9 + 32 G ^{2}}{2 G ^{2}}

True

, x = \frac{9 - 3 9 + 32 G ^{2}}{2 G ^{2}}

True

The solutions are

x = \frac{9 + 3 9 + 32 G ^{2}}{2 G ^{2}}, x = \frac{9 - 3 9 + 32 G ^{2}}{2 G ^{2}}

(2 x + 1)^{\frac{1}{3}} = - 1

2 x + 49 + 7 = x

x + 4 x + 1 = 5
