3x^2-3x-36=0

Solution

3 x^{2} - 3 x - 36 = 0

Solution

x = 4, x = - 3

Solution steps

3 x^{2} - 3 x - 36 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 3 ) \pm ( - 3 ) ^{2} - 4 \cdot 3 ( - 36 )}{2 \cdot 3}

(- 3)^{2} - 4 \cdot 3 (- 36) = 21

x_{1, 2} = \frac{- ( - 3 ) \pm 21}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- ( - 3 ) + 21}{2 \cdot 3}, x_{2} = \frac{- ( - 3 ) - 21}{2 \cdot 3}

x = \frac{- ( - 3 ) + 21}{2 \cdot 3} : 4

x = \frac{- ( - 3 ) - 21}{2 \cdot 3} : - 3

The solutions to the quadratic equation are:

x = 4, x = - 3
