sqrt(x)=8x-9

Solution

x = 8 x - 9

Solution

x = \frac{81}{64}

+1

Decimal

x = 1.265625

Solution steps

x = 8 x - 9

Square both sides:

x = 64 x^{2} - 144 x + 81

x = 64 x^{2} - 144 x + 81

Solve

x = 64 x^{2} - 144 x + 81 : x = \frac{81}{64}, x = 1

x = \frac{81}{64}, x = 1

Verify Solutions:

x = \frac{81}{64}

True

, x = 1

False

The solution is

x = \frac{81}{64}

4 x + 8 = 4 2 x - 2

\frac{1}{x} = 1

sqrt(x+9)+sqrt(x)=9

x + 9 + x = 9

sqrt(6+x-x^2)=1-x

6 + x - x^{2} = 1 - x

x - 3 = 9
