sqrt(x+1)=8-2x

Solution

x + 1 = 8 - 2 x

Solution

x = 3

Solution steps

x + 1 = 8 - 2 x

Square both sides:

x + 1 = 64 - 32 x + 4 x^{2}

x + 1 = 64 - 32 x + 4 x^{2}

Solve

x + 1 = 64 - 32 x + 4 x^{2} : x = \frac{21}{4}, x = 3

x = \frac{21}{4}, x = 3

Verify Solutions:

x = \frac{21}{4}

False

, x = 3

True

The solution is

x = 3
