-x^2+11x-28=0

Solution

- x^{2} + 11 x - 28 = 0

Solution

x = 4, x = 7

Solution steps

- x^{2} + 11 x - 28 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 11 \pm 1 1 ^{2} - 4 ( - 1 ) ( - 28 )}{2 ( - 1 )}

1 1^{2} - 4 (- 1) (- 28) = 3

x_{1, 2} = \frac{- 11 \pm 3}{2 ( - 1 )}

Separate the solutions

x_{1} = \frac{- 11 + 3}{2 ( - 1 )}, x_{2} = \frac{- 11 - 3}{2 ( - 1 )}

x = \frac{- 11 + 3}{2 ( - 1 )} : 4

x = \frac{- 11 - 3}{2 ( - 1 )} : 7

The solutions to the quadratic equation are:

x = 4, x = 7
