9 W^{2} - 27 W + 20 = 0

W = \frac{5}{3}, W = \frac{4}{3}

Decimal

W = 1.66666 \dots, W = 1.33333 \dots

Solution steps

9 W^{2} - 27 W + 20 = 0

Solve with the quadratic formula

W_{1, 2} = \frac{- ( - 27 ) \pm ( - 27 ) ^{2} - 4 \cdot 9 \cdot 20}{2 \cdot 9}

(- 27)^{2} - 4 \cdot 9 \cdot 20 = 3

W_{1, 2} = \frac{- ( - 27 ) \pm 3}{2 \cdot 9}

Separate the solutions

W_{1} = \frac{- ( - 27 ) + 3}{2 \cdot 9}, W_{2} = \frac{- ( - 27 ) - 3}{2 \cdot 9}

W = \frac{- ( - 27 ) + 3}{2 \cdot 9} : \frac{5}{3}

W = \frac{- ( - 27 ) - 3}{2 \cdot 9} : \frac{4}{3}

The solutions to the quadratic equation are:

W = \frac{5}{3}, W = \frac{4}{3}

15 + 3 x^{2} = 24

x^{2} - 4 x + 8

9 x^{2} + 60 x + 95 = - 5

4 z^{2} - 11 z + 4 = 0

x^{2} + 4 x + 5 = 0
