`(2a^2+3b^2)(5a^2-6b^2)`

If a/b=7/3 then find the value of (5a+3b)/(5a-3b) and (5a^2+3b^2)/(5a^2-3b^2)

If a/b=2/3 then find the values of expressions: (5a^2+2b^2)/(5a^2-2b^2)

The product (a+b)(a-b)(a^2-a b+b^2)(a^2+a b+b^2) is equal to: (a) a^6+b^6 (b) a^6-b^6 (c) a^3-b^3 (d) a^3+b^3

Factorise (Using factor theorem ) : 2a^(3)-5a^(2)b+6ab^(2)+3b^(3)

Find the product: (a^2+2b^2)(5a-3b)

If a:b=2:3, then the value of (5a^(3)-2a^(2)b):(3ab^(2)-b^(3)) is :

If [(a+4, 3b),(8 , -6)] = [(2a+2, b^2 +2), (8, b^2 - 5b)] , find the values of a and b.

Find the division of {a^3+8-9b(3b^2-2a)}-:(a^2+9b^2+4-2a+3ab+6b)

If 2a=b, the pair of equations ax+by=2a^(2)-3b^(2),x+2y=2a-6b possess
