2 x^{2} - 8 x - 10 = x + 8

x = 6, x = - \frac{3}{2}

Solution steps

2 x^{2} - 8 x - 10 = x + 8

Move

8

to the left side

2 x^{2} - 8 x - 18 = x

Move

x

to the left side

2 x^{2} - 9 x - 18 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 9 ) \pm ( - 9 ) ^{2} - 4 \cdot 2 ( - 18 )}{2 \cdot 2}

(- 9)^{2} - 4 \cdot 2 (- 18) = 15

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

Separate the solutions

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

x = \frac{- ( - 9 ) + 15}{2 \cdot 2} : 6

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

The solutions to the quadratic equation are:

x = 6, x = - \frac{3}{2}

4 x^{2} - 16 x + 17

y, 5 x^{2} - 2 x y + 2 y^{2} - 2 y - 71 = 0

- 2 x^{2} + 6 x - 1 = 0

8 x^{2} - 9 x + 1 = 0

x (- 1 + x) = 0
