5 b^{2} - 11 b - 12 = 0

b = 3, b = - \frac{4}{5}

Decimal Notation

b = 3, b = - 0.8

Solution steps

5 b^{2} - 11 b - 12 = 0

Solve with the quadratic formula

b_{1, 2} = \frac{- ( - 11 ) \pm ( - 11 ) ^{2} - 4 \cdot 5 ( - 12 )}{2 \cdot 5}

(- 11)^{2} - 4 \cdot 5 (- 12) = 19

b_{1, 2} = \frac{- ( - 11 ) \pm 19}{2 \cdot 5}

Separate the solutions

b_{1} = \frac{- ( - 11 ) + 19}{2 \cdot 5}, b_{2} = \frac{- ( - 11 ) - 19}{2 \cdot 5}

b = \frac{- ( - 11 ) + 19}{2 \cdot 5} : 3

b = \frac{- ( - 11 ) - 19}{2 \cdot 5} : - \frac{4}{5}

The solutions to the quadratic equation are:

b = 3, b = - \frac{4}{5}

50 x^{2} + 5 x - 21 = 0

(2 x - 1)^{2} = (x + 2) (x + 4) - 2

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

5 r^{2} - 245 = 0

- 16 a^{2} + 164 a + 36 = 0
