sqrt(4x^2+(45))=3x

4 x^{2} + (45) = 3 x

x = 3

Solution steps

4 x^{2} + (45) = 3 x

Square both sides:

4 x^{2} + 45 = 9 x^{2}

4 x^{2} + 45 = 9 x^{2}

Solve

4 x^{2} + 45 = 9 x^{2} : x = 3, x = - 3

x = 3, x = - 3

Verify Solutions:

x = 3

True

, x = - 3

False

The solution is

x = 3

x, 2 x - 3 = x - 3

3 x + 6 = x

4 x + 8 - x + 1 = 2
