9 x^{2} + 9 x - 2 = 14

x = \frac{- 3 + 73}{6}, x = - \frac{3 + 73}{6}

Decimal Notation

x = 0.92400 \dots, x = - 1.92400 \dots

Solution steps

9 x^{2} + 9 x - 2 = 14

Move

14

to the left side

9 x^{2} + 9 x - 16 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 9 \pm 9 ^{2} - 4 \cdot 9 ( - 16 )}{2 \cdot 9}

9^{2} - 4 \cdot 9 (- 16) = 373

x_{1, 2} = \frac{- 9 \pm 3 73}{2 \cdot 9}

Separate the solutions

x_{1} = \frac{- 9 + 3 73}{2 \cdot 9}, x_{2} = \frac{- 9 - 3 73}{2 \cdot 9}

x = \frac{- 9 + 3 73}{2 \cdot 9} : \frac{- 3 + 73}{6}

x = \frac{- 9 - 3 73}{2 \cdot 9} : - \frac{3 + 73}{6}

The solutions to the quadratic equation are:

x = \frac{- 3 + 73}{6}, x = - \frac{3 + 73}{6}

1 - (\frac{45}{53})^{2}

8 2^{\frac{3}{2}}

\frac{2 ^{- 1}}{3}

x^{2} - 5 x - 31 = 5

- 4 (4 x - 9) = 2 x
