9 x^{2} + 12 x = 4

x = \frac{2 ( 2 - 1 )}{3}, x = - \frac{2 ( 1 + 2 )}{3}

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 1 2 ^{2} - 4 \cdot 9 ( - 4 )}{2 \cdot 9}

1 2^{2} - 4 \cdot 9 (- 4) = 122

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

Separate the solutions

x_{1} = \frac{- 12 + 12 2}{2 \cdot 9}, x_{2} = \frac{- 12 - 12 2}{2 \cdot 9}

x = \frac{- 12 + 12 2}{2 \cdot 9} : \frac{2 ( 2 - 1 )}{3}

x = \frac{- 12 - 12 2}{2 \cdot 9} : - \frac{2 ( 1 + 2 )}{3}

The solutions to the quadratic equation are:

x = \frac{2 ( 2 - 1 )}{3}, x = - \frac{2 ( 1 + 2 )}{3}

15 x^{2} + x - 6

x^{2} - 9 = 0

3 x^{2} + 6 x - 24

f = 3 (15) + 2
