3 b^{2} - 10 b - 8 = 0

b = 4, b = - \frac{2}{3}

Decimal Notation

b = 4, b = - 0.66666 \dots

Solution steps

3 b^{2} - 10 b - 8 = 0

Solve with the quadratic formula

b_{1, 2} = \frac{- ( - 10 ) \pm ( - 10 ) ^{2} - 4 \cdot 3 ( - 8 )}{2 \cdot 3}

(- 10)^{2} - 4 \cdot 3 (- 8) = 14

b_{1, 2} = \frac{- ( - 10 ) \pm 14}{2 \cdot 3}

Separate the solutions

b_{1} = \frac{- ( - 10 ) + 14}{2 \cdot 3}, b_{2} = \frac{- ( - 10 ) - 14}{2 \cdot 3}

b = \frac{- ( - 10 ) + 14}{2 \cdot 3} : 4

b = \frac{- ( - 10 ) - 14}{2 \cdot 3} : - \frac{2}{3}

The solutions to the quadratic equation are:

b = 4, b = - \frac{2}{3}

12 - 4 x - x^{2} = 0

a, a^{2} - 2 ab + b^{2} = 0

27 x^{2} = 3

- 5 x^{2} + 25 x = - 120

r^{2} - 4 r - 91 + 7 = 0
