- x^{2} = 100 - 20 x

x = 10

Solution steps

- x^{2} = 100 - 20 x

Move

20 x

to the left side

- x^{2} + 20 x = 100

Move

100

to the left side

- x^{2} + 20 x - 100 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 20 \pm 2 0 ^{2} - 4 ( - 1 ) ( - 100 )}{2 ( - 1 )}

2 0^{2} - 4 (- 1) (- 100) = 0

x_{1, 2} = \frac{- 20 \pm 0}{2 ( - 1 )}

x = \frac{- 20}{2 ( - 1 )}

\frac{- 20}{2 ( - 1 )} = 10

x = 10

The solution to the quadratic equation is:

x = 10

4 - \frac{8 x}{2} = 24

\frac{3}{8}

(- 5 m^{2} - 8) - (- 3 m^{2} + m + 2)

2 x^{2} + 3 x = - 5

\frac{2 x + 23}{5} = 3
