3 x^{2} - 6 x = 45

x = 5, x = - 3

Solution steps

3 x^{2} - 6 x = 45

Move

45

to the left side

3 x^{2} - 6 x - 45 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 6 ) \pm ( - 6 ) ^{2} - 4 \cdot 3 ( - 45 )}{2 \cdot 3}

(- 6)^{2} - 4 \cdot 3 (- 45) = 24

x_{1, 2} = \frac{- ( - 6 ) \pm 24}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- ( - 6 ) + 24}{2 \cdot 3}, x_{2} = \frac{- ( - 6 ) - 24}{2 \cdot 3}

x = \frac{- ( - 6 ) + 24}{2 \cdot 3} : 5

x = \frac{- ( - 6 ) - 24}{2 \cdot 3} : - 3

The solutions to the quadratic equation are:

x = 5, x = - 3

2 x^{2} = - 6 x + 1

x, x^{2} - (2 p - 1) x + (p^{2} - p - 20) = 0

x^{2} + 5 x + 5 = 0

x, t^{2} = 240 x^{2}

12 x^{2} - 10 x + 1 = 7
