Question

factorise the following 27a²-486²​

Answer 1

hey mate

given here

27a^2-486^2

=(3√3a)^2- (486)^2

using formula

x^2 - y^2= (x+y)(x-y)

so,

=(3√3a+486)(3√3a-486).

or

I hopes its helps u.

Answer 2

Answer:

27a²-486² = (3a√3)^2 - (9√6)^2

= (3a√3 - 9√6) (3a√3 + 9√6).

➡️[ By a^2 - b^2 = (a+b) (a-b) ]
