please solve this fast because I have lost many points for these questions

Answer 1

$8.(a) \frac{10x}{5 } - \frac{25}{5}$
$= 2x - 5$
$(b) \frac{5(2x - 5)}{(2x - 5)}$
$= 5$

Answer 2

(8)

a)

Given : (10x - 25) ÷ 5

⇒ 5(2x - 5) ÷ 5

⇒ (2x - 5).

(b)

Given : (10x - 25) ÷ (2x - 5)

⇒ 5(2x - 5) ÷ (2x - 5)

⇒ 5.

(9)

(a)

Given : (m^2 - 14m - 32) ÷ (m + 2)

⇒ (m^2 - 16m + 2m - 32) ÷ (m + 2)

⇒ (m + 2)(m - 16) ÷ (m + 2)

⇒ m - 16.

(b)

Given : (5p^2 - 25p + 20) ÷ (p - 1)

⇒ 5(p^2 - 5p + 4) ÷ (p - 1)

⇒ 5(p^2 - p - 4p + 4) ÷ (p - 1)

⇒ 5(p - 1)(p - 4) ÷ (p - 1)

⇒ 5(p - 4).

Hope it helps!
