3 x^{2} - 15 x = - 12

x = 4, x = 1

Solution steps

3 x^{2} - 15 x = - 12

Move

12

to the left side

3 x^{2} - 15 x + 12 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 15 ) \pm ( - 15 ) ^{2} - 4 \cdot 3 \cdot 12}{2 \cdot 3}

(- 15)^{2} - 4 \cdot 3 \cdot 12 = 9

x_{1, 2} = \frac{- ( - 15 ) \pm 9}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- ( - 15 ) + 9}{2 \cdot 3}, x_{2} = \frac{- ( - 15 ) - 9}{2 \cdot 3}

x = \frac{- ( - 15 ) + 9}{2 \cdot 3} : 4

x = \frac{- ( - 15 ) - 9}{2 \cdot 3} : 1

The solutions to the quadratic equation are:

x = 4, x = 1

4 x + 5 > 17

\frac{1}{27} x^{3} + \frac{1}{125} y^{3}

(x + 4)^{2} = 36
