2 x^{2} + 3 x - 90 = 0

x = 6, x = - \frac{15}{2}

Decimal Notation

x = 6, x = - 7.5

Solution steps

2 x^{2} + 3 x - 90 = 0

Solve with the quadratic formula

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

3^{2} - 4 \cdot 2 (- 90) = 27

x_{1, 2} = \frac{- 3 \pm 27}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- 3 + 27}{2 \cdot 2}, x_{2} = \frac{- 3 - 27}{2 \cdot 2}

x = \frac{- 3 + 27}{2 \cdot 2} : 6

x = \frac{- 3 - 27}{2 \cdot 2} : - \frac{15}{2}

The solutions to the quadratic equation are:

x = 6, x = - \frac{15}{2}

x, y = (x - 1)^{2}

x^{2} = (x - 2) (3 x - 4)

x^{2} + 6 x - 2 = 0

- x^{2} - 18 x - 8 = - 6 x^{2}

x^{2} - 4 x + 31 = 0
