- 30 m^{2} + 65 m + 40 = 0

m = - \frac{1}{2}, m = \frac{8}{3}

Decimal Notation

m = - 0.5, m = 2.66666 \dots

Solution steps

- 30 m^{2} + 65 m + 40 = 0

Solve with the quadratic formula

m_{1, 2} = \frac{- 65 \pm 6 5 ^{2} - 4 ( - 30 ) \cdot 40}{2 ( - 30 )}

6 5^{2} - 4 (- 30) \cdot 40 = 95

m_{1, 2} = \frac{- 65 \pm 95}{2 ( - 30 )}

Separate the solutions

m_{1} = \frac{- 65 + 95}{2 ( - 30 )}, m_{2} = \frac{- 65 - 95}{2 ( - 30 )}

m = \frac{- 65 + 95}{2 ( - 30 )} : - \frac{1}{2}

m = \frac{- 65 - 95}{2 ( - 30 )} : \frac{8}{3}

The solutions to the quadratic equation are:

m = - \frac{1}{2}, m = \frac{8}{3}

x^{2} + 5 = 9 x

2 x^{2} - 294 = 0

x^{2} + 5 = 86

m^{2} + 2 m - 7 = 0

z^{2} - 16 z + 61 = 2 z \cdot 20
