Let's divide by arranging in decreasing powers of variables.
`(4a^2 - 9b^2) by (2a + 3b)`

Let's factorise a^3 - 9b^3 + (a + b)^3

Factorise : 4a^(2)-12ab+9b^(2)+2a-3b

Let's express the following in the product from using formula. (a^2 + b^2) (a^2 - b^2) (a^4 + b^4) (a^8 + b^8)

Let's divide:- (m^2 + 4m - 21) by (m-3)

Let's divide:- (2a^4 - a^3 - 2a^2 + 5a - 1) by (2a^2 + a - 3)

Using formula let's show that. (a+2b)^2 + (a-2b)^2 = 2(a^2 + 4b^2)

Let's express the following in perfect square and hence find the value. 25a^2 - 30ab + 9b^2 when a = 1, b=1

Let's resolve into factor:- 6(a + b)^2 + 5(a^2 - b^2)-6(a-b )^2

Let's resolve into factors: x^2 - bx - (a + 3b)(a+2b)

Let's add the following :- (7a - 8b + 2c) and (2a + 3b -d)
