Factorize: (i) 6(2a+3b)^(2)-8(2a+3b)

-3 (a + b) + 4 (2a - 3b) - (2a - b)

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

Simplify each of the following: -5(a+b)+2(2a-b)+4a-7 -3(a+b)+4(2a-3b)-(2a-b)

Simplify each of the following: -5(a+b)+2(2a-b)+4a-7 -3(a+b)+4(2a-3b)-(2a-b)

The factors of 8a^3+b^3-6a b+1 are (a) (2a+b-1)(4a^2+b^2+1-3a b-2a) (b) (2a-b+1)(4a^2+b^2-4a b+1-2a+b) (c) (2a+b+1)(4a^2+b^2+1-2a b-b-2a) (d) (2a-1+b)(4a^2+1-4a-b-2a b)

Simplify : (Use formulae) (2a-3b+4c)^2-(2a+3b-4c)^2

Evaluate : (viii) (3a^(2) - 4b^(2) ) (8a^(2) - 3b^(2) )

If sin^4 A/a+cos^4 A/b=1/(a+b) , then the value of sin^8 A/a^3+cos^8 A/b^3 is equal to (A) 1/(a+b)^3 (B) (a^3b^3)/(a+b)^3 (C) (a^2b^2)/(a+b)^2 (D) none of these

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
