2 W^{2} + 5 W - 63 = 0

W = \frac{9}{2}, W = - 7

Decimal Notation

W = 4.5, W = - 7

Solution steps

2 W^{2} + 5 W - 63 = 0

Solve with the quadratic formula

W_{1, 2} = \frac{- 5 \pm 5 ^{2} - 4 \cdot 2 ( - 63 )}{2 \cdot 2}

5^{2} - 4 \cdot 2 (- 63) = 23

W_{1, 2} = \frac{- 5 \pm 23}{2 \cdot 2}

Separate the solutions

W_{1} = \frac{- 5 + 23}{2 \cdot 2}, W_{2} = \frac{- 5 - 23}{2 \cdot 2}

W = \frac{- 5 + 23}{2 \cdot 2} : \frac{9}{2}

W = \frac{- 5 - 23}{2 \cdot 2} : - 7

The solutions to the quadratic equation are:

W = \frac{9}{2}, W = - 7

x^{2} - 10 x + 16

y^{2} - 6 y - 27 = 0

4 x^{2} - 8 a x + 5 x - 10 a = 0

5 x^{2} - 9 x + 18 = 4 x^{2}

x^{2} + 3 = 0
