sqrt(9x^2)=2x+1

9 x^{2} = 2 x + 1

x = - \frac{1}{5}, x = 1

Decimal Notation

x = - 0.2, x = 1

Solution steps

9 x^{2} = 2 x + 1

Square both sides:

9 x^{2} = 4 x^{2} + 4 x + 1

9 x^{2} = 4 x^{2} + 4 x + 1

Solve

9 x^{2} = 4 x^{2} + 4 x + 1 : x = - \frac{1}{5}, x = 1

x = - \frac{1}{5}, x = 1

Verify Solutions:

x = - \frac{1}{5}

True

, x = 1

True

The solutions are

x = - \frac{1}{5}, x = 1

x + 6 = 25 x

x + 5 + 7 = 10

a^{2} = a

x^{2} + 4 x + 3 = x^{2} + 4 x + 5

3 x - 5 = 2
