`(2a+3b)^3+(2a-3b)^3`

i) (2a-3b)^3

Find the product of the following binomials; (i) (2x+3/y)(2x-3/y) (ii) (2a^3+b^3)(2a^3-b^3)

Factorize: 4\ (x+y)^2-28 y(x+y)+49 y^2 (2a+3b)^2+2(2a+3b)(2a-3b)+(2a-3b)^2

Evaluate : (i) ((a)/(2b)+(2b)/(a))^(2)-((a)/(2b)-(2b)/(a))^(2)-4 (ii) (4a+3b)^(2)-(4a-3b)^(2)+48ab

Simplify (a+b)(2a-3b+c)-(2a-3b)c.

Find and correct the errors in the following mathematical statements. (2a + 3b) (a - b) = 2a^2 - 3b^2

Factorise (2a+ b)^(3) - (a+ 2b)^(3)

a^2b^3\ X\ 2a b^2 is equal to: (a) 2a^3b^4 (b) 2a^3b^5 (c) 2a b (d) a^3b^5

The value of [{(a^2-b^2)^3+(b^2-c^2)^3+(c^2-a^2)^3}/{(a-b)^3+(b-c)^3+(c-a)^3}] = (1) 3(a+b)(b+c)(c+a) (2) 3(a-b)(b-c)(c-a) (3) (a+b)(b+c)(c+a) (4) 1

Simplify : 2/3 (2a-3b) -3/4 (2a +5/3 b)
