2 W^{2} + 3 W - 77 = 0

W = \frac{11}{2}, W = - 7

Decimal Notation

W = 5.5, W = - 7

Solution steps

2 W^{2} + 3 W - 77 = 0

Solve with the quadratic formula

W_{1, 2} = \frac{- 3 \pm 3 ^{2} - 4 \cdot 2 ( - 77 )}{2 \cdot 2}

3^{2} - 4 \cdot 2 (- 77) = 25

W_{1, 2} = \frac{- 3 \pm 25}{2 \cdot 2}

Separate the solutions

W_{1} = \frac{- 3 + 25}{2 \cdot 2}, W_{2} = \frac{- 3 - 25}{2 \cdot 2}

W = \frac{- 3 + 25}{2 \cdot 2} : \frac{11}{2}

W = \frac{- 3 - 25}{2 \cdot 2} : - 7

The solutions to the quadratic equation are:

W = \frac{11}{2}, W = - 7

1 (\frac{1}{3})

25 x^{2} + 16 < 40 x

\frac{x}{3} - 3 = - 12

∣ 4 x - 1 ∣ = 18
