Use the sum-product pattern

2−4−5

x^{2}{\color{#c92786}{-4x}}-5x2−4x−5

2+−5−5

x^{2}+{\color{#c92786}{x}}{\color{#c92786}{-5x}}-5x2+x−5x−5

2

Common factor from the two pairs

2+−5−5

x^{2}+x-5x-5x2+x−5x−5

(+1)−5(+1)

x(x+1)-5(x+1)x(x+1)−5(x+1)

Rewrite in factored form

(+1)−5(+1)

x(x+1)-5(x+1)x(x+1)−5(x+1)

(−5)(+1)

(x-5)(x+1)(x−5)(x+1)

Solution

(−5)(+1)
