- x^{2} + 2 = x

x = - 2, x = 1

Solution steps

- x^{2} + 2 = x

Move

x

to the left side

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

Write in the standard form

a x^{2} + b x + c = 0

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

Solve with the quadratic formula

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

(- 1)^{2} - 4 (- 1) \cdot 2 = 3

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

Separate the solutions

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

x = \frac{- ( - 1 ) + 3}{2 ( - 1 )} : - 2

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

The solutions to the quadratic equation are:

x = - 2, x = 1

3 x^{2} - 8 x - 19 = (x - 1)^{2}

5 x^{2} + 17 x = - 6

x^{2} - 2 x + 1 = 36

2 x^{2} + 8 x - 13 = 0

2 (x - 3)^{2} - 15 = 0
