Question

[4(a)-b²/ab -16] [(a)-b²-ab/ab] :a³-b³/ab​

Answer 1

Answer:

Here’s a simple algebraic proof starting with the expansion of (a-b)^3

explanation

(a-b)^3 = a^3–3ab(a-b)-b^3

(a-b)^3+ 3ab(a-b)=a^3 - b^3

(a-b)((a-b)^2+3ab) =a^3-b^3

(a-b)(a^-2ab+b^2+3ab)=a^3-b^3

a^3-b^3=(a-b)(a^2+ab+b^2)
