9 x^{2} - 12 x = - 4

x = \frac{2}{3}

Decimal Notation

x = 0.66666 \dots

Solution steps

9 x^{2} - 12 x = - 4

Move

4

to the left side

9 x^{2} - 12 x + 4 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 12 ) \pm ( - 12 ) ^{2} - 4 \cdot 9 \cdot 4}{2 \cdot 9}

(- 12)^{2} - 4 \cdot 9 \cdot 4 = 0

x_{1, 2} = \frac{- ( - 12 ) \pm 0}{2 \cdot 9}

x = \frac{- ( - 12 )}{2 \cdot 9}

\frac{- ( - 12 )}{2 \cdot 9} = \frac{2}{3}

x = \frac{2}{3}

The solution to the quadratic equation is:

x = \frac{2}{3}

5 x^{2} - 9 x - 18 = 0

- 2 x^{2} + 7 x - 5 = 0

3 x^{2} + 192 = 0

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

z^{2} - z = 0
