9 x^{2} = 4 x

x = 0, x = \frac{4}{9}

Decimal Notation

x = 0, x = 0.44444 \dots

Solution steps

9 x^{2} = 4 x

Move

4 x

to the left side

9 x^{2} - 4 x = 0

Factor

9 x^{2} - 4 x : x (9 x - 4)

x (9 x - 4) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or 9 x - 4 = 0

Solve

9 x - 4 = 0 : x = \frac{4}{9}

The solutions to the quadratic equation are:

x = 0, x = \frac{4}{9}

x^{2} - 300 x + 20000 = 0

2 x^{2} - 3 + 1 = 0

390 = 0.9 q^{2} - 18 q + 120

2 k^{2} - 4 (1) (9) = 0

- 2 x^{2} + 12 x - 14
