Solution

x < 4 or x > 5

+1

Solution steps

5 - x < (5 - x)^{2}

Rewrite in standard form

- x^{2} + 9 x - 20 < 0

Factor

- x^{2} + 9 x - 20 : - (x - 4) (x - 5)

- (x - 4) (x - 5) < 0

Multiply both sides by

- 1

(reverse the inequality)

(- (x - 4) (x - 5)) (- 1) > 0 \cdot (- 1)

Simplify

(x - 4) (x - 5) > 0
