5 b^{2} + 19 b - 30 = 0

b = \frac{6}{5}, b = - 5

Decimal Notation

b = 1.2, b = - 5

Solution steps

5 b^{2} + 19 b - 30 = 0

Solve with the quadratic formula

b_{1, 2} = \frac{- 19 \pm 1 9 ^{2} - 4 \cdot 5 ( - 30 )}{2 \cdot 5}

1 9^{2} - 4 \cdot 5 (- 30) = 31

b_{1, 2} = \frac{- 19 \pm 31}{2 \cdot 5}

Separate the solutions

b_{1} = \frac{- 19 + 31}{2 \cdot 5}, b_{2} = \frac{- 19 - 31}{2 \cdot 5}

b = \frac{- 19 + 31}{2 \cdot 5} : \frac{6}{5}

b = \frac{- 19 - 31}{2 \cdot 5} : - 5

The solutions to the quadratic equation are:

b = \frac{6}{5}, b = - 5

(x - 2) (2 x - 13) = - 4

6 x^{2} - 6 x - 36

- x + 5 + 6 x = 1 + 5 x + 3
