Answer:
Step-by-step explanation:
2(x+7.9)=20
x+7.9=20/2=10
x=10-7.9=2.1
2)
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>
---------
4)
<h2>
x^2 - 25 = (x - 5)(x + 5)</h2>
Answer:
