Question

Gla)=a-4
Ha)=a* +2-a
Find gla). Mla)

Answer 1

a³ - 5a² + 6a - 8

Explanation:

Given we require

g(a) × h(a)

= (a - 4)(a² + 2 - a)

Each term in the second factor is multiplied by each term in the first factor, that is

a(a² + 2 - a) - 4(a² + 2 - a) ← distribute both parenthesis

= a³ + 2a - a² - 4a² - 8 + 4a ← collect like terms

= a³ - 5a² + 6a - 8 ← in standard form

Answer 2

2

Explanation:

a is 2 so 2+2=4 and 4-2=2 so the answer would be 2.
