x^2 - 14x - 32 = x^2 - 16x + 2x - 32 = x(x-16) + 2(x-16) = (x - 16)(x + 2)

<h2>⇒ x^2 - 14x - 32 = (x - 16)(x + 2)</h2>

3)

2n^2 - 7n - 15 =

= 2n^2 - 10n + 3n - 15 =

= 2n(n - 5) + 3(n - 5) =

= (n - 5)(2n + 3)

<h2>⇒ 2n^2 - 7n - 15 = (n - 5)(2n + 3)</h2>

prohojiy [21]

Answer:

72

Step-by-step explanation

48 + k+l =180

48 +90+l =180

138 +l = 180

l=180 - 138

l = 42

now

l+m+n= 180

42 +m+66 =180

108+m= 180

m= 180 -108 m =72
