- 3 x^{2} - 31 x - 72 = - x

x = - 6, x = - 4

Solution steps

- 3 x^{2} - 31 x - 72 = - x

Move

x

to the left side

- 3 x^{2} - 30 x - 72 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 30 ) \pm ( - 30 ) ^{2} - 4 ( - 3 ) ( - 72 )}{2 ( - 3 )}

(- 30)^{2} - 4 (- 3) (- 72) = 6

x_{1, 2} = \frac{- ( - 30 ) \pm 6}{2 ( - 3 )}

Separate the solutions

x_{1} = \frac{- ( - 30 ) + 6}{2 ( - 3 )}, x_{2} = \frac{- ( - 30 ) - 6}{2 ( - 3 )}

x = \frac{- ( - 30 ) + 6}{2 ( - 3 )} : - 6

x = \frac{- ( - 30 ) - 6}{2 ( - 3 )} : - 4

The solutions to the quadratic equation are:

x = - 6, x = - 4

c^{2} = 5^{2} - 4^{2}

91 - q^{2} = 1 + q

(x - 8)^{2} = 2

x^{2} + 1 = 3 x + 1

3 x - 5 x^{2} + 8 x = 7 + 5 x
