x^{2} - 3 x = 2 x + 14

x = 7, x = - 2

Solution steps

x^{2} - 3 x = 2 x + 14

Move

14

to the left side

x^{2} - 3 x - 14 = 2 x

Move

2 x

to the left side

x^{2} - 5 x - 14 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 5 ) \pm ( - 5 ) ^{2} - 4 \cdot 1 \cdot ( - 14 )}{2 \cdot 1}

(- 5)^{2} - 4 \cdot 1 \cdot (- 14) = 9

x_{1, 2} = \frac{- ( - 5 ) \pm 9}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 5 ) + 9}{2 \cdot 1}, x_{2} = \frac{- ( - 5 ) - 9}{2 \cdot 1}

x = \frac{- ( - 5 ) + 9}{2 \cdot 1} : 7

x = \frac{- ( - 5 ) - 9}{2 \cdot 1} : - 2

The solutions to the quadratic equation are:

x = 7, x = - 2

23 = x^{2} + 7

x, 432 = 3 x^{2}

x^{2} - 8 x + 5 = 0

X^{2} + 3 X + 2 = 0

12 x^{2} + 25 x = 7
