0 = 5 x^{2} + 35 x - 90

x = 2, x = - 9

Solution steps

0 = 5 x^{2} + 35 x - 90

Switch sides

5 x^{2} + 35 x - 90 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 35 \pm 3 5 ^{2} - 4 \cdot 5 ( - 90 )}{2 \cdot 5}

3 5^{2} - 4 \cdot 5 (- 90) = 55

x_{1, 2} = \frac{- 35 \pm 55}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- 35 + 55}{2 \cdot 5}, x_{2} = \frac{- 35 - 55}{2 \cdot 5}

x = \frac{- 35 + 55}{2 \cdot 5} : 2

x = \frac{- 35 - 55}{2 \cdot 5} : - 9

The solutions to the quadratic equation are:

x = 2, x = - 9

x^{2} - 4 x + 1 = 0

w^{2} + 6 w - 11 = 0

x^{2} - 4 x + 3 = 0

- 9 x^{2} = 0

x^{2} + x = \frac{11}{4}
