- x^{2} + 16 x = 63

x = 7, x = 9

Solution steps

- x^{2} + 16 x = 63

Move

63

to the left side

- x^{2} + 16 x - 63 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 16 \pm 1 6 ^{2} - 4 ( - 1 ) ( - 63 )}{2 ( - 1 )}

1 6^{2} - 4 (- 1) (- 63) = 2

x_{1, 2} = \frac{- 16 \pm 2}{2 ( - 1 )}

Separate the solutions

x_{1} = \frac{- 16 + 2}{2 ( - 1 )}, x_{2} = \frac{- 16 - 2}{2 ( - 1 )}

x = \frac{- 16 + 2}{2 ( - 1 )} : 7

x = \frac{- 16 - 2}{2 ( - 1 )} : 9

The solutions to the quadratic equation are:

x = 7, x = 9

0 = - x^{2} - 12 x + 17

4 = x^{2} - 4 x + 4

x, x^{2} - 2 y^{2} = 0

x^{2} - 6 x - 7 = 0

x^{2} + 7 = 16
