15 x^{2} - 16 x - 15 = 0

x = \frac{5}{3}, x = - \frac{3}{5}

Decimal Notation

x = 1.66666 \dots, x = - 0.6

Solution steps

15 x^{2} - 16 x - 15 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 16 ) \pm ( - 16 ) ^{2} - 4 \cdot 15 ( - 15 )}{2 \cdot 15}

(- 16)^{2} - 4 \cdot 15 (- 15) = 34

x_{1, 2} = \frac{- ( - 16 ) \pm 34}{2 \cdot 15}

Separate the solutions

x_{1} = \frac{- ( - 16 ) + 34}{2 \cdot 15}, x_{2} = \frac{- ( - 16 ) - 34}{2 \cdot 15}

x = \frac{- ( - 16 ) + 34}{2 \cdot 15} : \frac{5}{3}

x = \frac{- ( - 16 ) - 34}{2 \cdot 15} : - \frac{3}{5}

The solutions to the quadratic equation are:

x = \frac{5}{3}, x = - \frac{3}{5}

(x + 7) (x - 7) = - 3

2 x^{2} + 36 x + 34 = 0

3 k^{2} - k - 12 = - 6

x^{2} - 5 x + 3 = 0

(3 k + 4)^{2} + 15 = 0
