3 x^{2} - 21 x = 24

x = 8, x = - 1

Solution steps

3 x^{2} - 21 x = 24

Move

24

to the left side

3 x^{2} - 21 x - 24 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 21 ) \pm ( - 21 ) ^{2} - 4 \cdot 3 ( - 24 )}{2 \cdot 3}

(- 21)^{2} - 4 \cdot 3 (- 24) = 27

x_{1, 2} = \frac{- ( - 21 ) \pm 27}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- ( - 21 ) + 27}{2 \cdot 3}, x_{2} = \frac{- ( - 21 ) - 27}{2 \cdot 3}

x = \frac{- ( - 21 ) + 27}{2 \cdot 3} : 8

x = \frac{- ( - 21 ) - 27}{2 \cdot 3} : - 1

The solutions to the quadratic equation are:

x = 8, x = - 1

x^{3} - 5 x^{2} + 6 x

0 = - 16 x^{2} + 64 x + 80
