11 x - x^{2} = 18

x = 2, x = 9

Solution steps

11 x - x^{2} = 18

Move

18

to the left side

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

Write in the standard form

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

- x^{2} + 11 x - 18 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 11 \pm 1 1 ^{2} - 4 ( - 1 ) ( - 18 )}{2 ( - 1 )}

1 1^{2} - 4 (- 1) (- 18) = 7

x_{1, 2} = \frac{- 11 \pm 7}{2 ( - 1 )}

Separate the solutions

x_{1} = \frac{- 11 + 7}{2 ( - 1 )}, x_{2} = \frac{- 11 - 7}{2 ( - 1 )}

x = \frac{- 11 + 7}{2 ( - 1 )} : 2

x = \frac{- 11 - 7}{2 ( - 1 )} : 9

The solutions to the quadratic equation are:

x = 2, x = 9

4 0^{2} + 4 0^{2} = c^{2}

Y, Y^{2} = X^{3} - 4 X

x^{2} - 176 = 0

t, ((a - c) - (b t + d t))^{2} = (r + t)^{2}

- 2 x^{2} + 9 x - 5 = x^{2} - 12 x + 25
