3 x^{2} - 8 x - 20 = - 9

x = \frac{11}{3}, x = - 1

Decimal Notation

x = 3.66666 \dots, x = - 1

Solution steps

3 x^{2} - 8 x - 20 = - 9

Move

9

to the left side

3 x^{2} - 8 x - 11 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 8 ) \pm ( - 8 ) ^{2} - 4 \cdot 3 ( - 11 )}{2 \cdot 3}

(- 8)^{2} - 4 \cdot 3 (- 11) = 14

x_{1, 2} = \frac{- ( - 8 ) \pm 14}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- ( - 8 ) + 14}{2 \cdot 3}, x_{2} = \frac{- ( - 8 ) - 14}{2 \cdot 3}

x = \frac{- ( - 8 ) + 14}{2 \cdot 3} : \frac{11}{3}

x = \frac{- ( - 8 ) - 14}{2 \cdot 3} : - 1

The solutions to the quadratic equation are:

x = \frac{11}{3}, x = - 1

x + 1 = x (x - 4)

x, x^{2} - 50 y^{2} - 10 x + 25 = 0

x^{2} + 24 x + 132

x^{2} + 23 x + 132 = 0

x^{2} + 3 x - 22 = 0
