2 m^{2} - 13 m - 45 = 0

m = 9, m = - \frac{5}{2}

Decimal Notation

m = 9, m = - 2.5

Solution steps

2 m^{2} - 13 m - 45 = 0

Solve with the quadratic formula

m_{1, 2} = \frac{- ( - 13 ) \pm ( - 13 ) ^{2} - 4 \cdot 2 ( - 45 )}{2 \cdot 2}

(- 13)^{2} - 4 \cdot 2 (- 45) = 23

m_{1, 2} = \frac{- ( - 13 ) \pm 23}{2 \cdot 2}

Separate the solutions

m_{1} = \frac{- ( - 13 ) + 23}{2 \cdot 2}, m_{2} = \frac{- ( - 13 ) - 23}{2 \cdot 2}

m = \frac{- ( - 13 ) + 23}{2 \cdot 2} : 9

m = \frac{- ( - 13 ) - 23}{2 \cdot 2} : - \frac{5}{2}

The solutions to the quadratic equation are:

m = 9, m = - \frac{5}{2}

3 a^{2} + 9 a - 30 = 0

x, 5 x^{2} + 3 = 2 y^{3} + 5

x^{2} + 5 x - 22 = 8 x + 32

16 x^{2} - 225 = 0

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