w^{2} - \frac{1}{15} w - \frac{2}{15} = 0

w = \frac{2}{5}, w = - \frac{1}{3}

Decimal Notation

w = 0.4, w = - 0.33333 \dots

Solution steps

w^{2} - \frac{1}{15} w - \frac{2}{15} = 0

Multiply both sides by

15

15 w^{2} - w - 2 = 0

Solve with the quadratic formula

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

(- 1)^{2} - 4 \cdot 15 (- 2) = 11

w_{1, 2} = \frac{- ( - 1 ) \pm 11}{2 \cdot 15}

Separate the solutions

w_{1} = \frac{- ( - 1 ) + 11}{2 \cdot 15}, w_{2} = \frac{- ( - 1 ) - 11}{2 \cdot 15}

w = \frac{- ( - 1 ) + 11}{2 \cdot 15} : \frac{2}{5}

w = \frac{- ( - 1 ) - 11}{2 \cdot 15} : - \frac{1}{3}

The solutions to the quadratic equation are:

w = \frac{2}{5}, w = - \frac{1}{3}

3 x^{2} + 6 x - 1

9 x^{2} - 32 = 0

x^{2} + 9 x - 1 = 3 x - 10

x^{2} + 10 x - 80 = 0

x^{2} - 2 x + 1 = 81
