0.02 w^{2} - 0.3 w - 20 = 0

w = 40, w = - 25

Solution steps

0.02 w^{2} - 0.3 w - 20 = 0

Multiply both sides by

100

2 w^{2} - 30 w - 2000 = 0

Solve with the quadratic formula

w_{1, 2} = \frac{- ( - 30 ) \pm ( - 30 ) ^{2} - 4 \cdot 2 ( - 2000 )}{2 \cdot 2}

(- 30)^{2} - 4 \cdot 2 (- 2000) = 130

w_{1, 2} = \frac{- ( - 30 ) \pm 130}{2 \cdot 2}

Separate the solutions

w_{1} = \frac{- ( - 30 ) + 130}{2 \cdot 2}, w_{2} = \frac{- ( - 30 ) - 130}{2 \cdot 2}

w = \frac{- ( - 30 ) + 130}{2 \cdot 2} : 40

w = \frac{- ( - 30 ) - 130}{2 \cdot 2} : - 25

The solutions to the quadratic equation are:

w = 40, w = - 25

36 k^{2} + 36 k^{2} + 36 k^{2} = (243)^{2}

x, x y - 3 y - x^{2} + 16 = 0

x^{2} + 18 x - 108 = 0

3 x^{2} - 96 x + 600 = 0

- 2 x^{2} - 8 x + 1 = 0
