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

x = 2, x = - 9

Solution steps

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

15 x + 15 = - 4 x^{2}

4 x^{2} + 12 x + 9 = 0

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

(x - 3)^{2} - 169 = 0

6 x^{2} = 7
