3x^2+3x-90=0

Solution

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

Solution

x = 5, x = - 6

Solution steps

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

Solve with the quadratic formula

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

3^{2} - 4 \cdot 3 (- 90) = 33

x_{1, 2} = \frac{- 3 \pm 33}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- 3 + 33}{2 \cdot 3}, x_{2} = \frac{- 3 - 33}{2 \cdot 3}

x = \frac{- 3 + 33}{2 \cdot 3} : 5

x = \frac{- 3 - 33}{2 \cdot 3} : - 6

The solutions to the quadratic equation are:

x = 5, x = - 6
