(2a+3b)(a-b)=2a^(2)-3b^(2)+5)^(2)

Incorrect: (2a+3b)(a-b)=2a^2+ab-3b^2 Correct: (2a+3b)(a-b)=2a^2+3ab-2ab-3b^2=2a^2+ab-3b^2 .

Simplify: 4a b(a-b)-6a^2(b-b^2)-3b^2(2a^2-a)+2a b(b-a)

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

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

a^(2)b^(3)x2ab^(2) is equal to: 2a^(3)b^(4)(b)2a^(3)b^(5)(c)2ab (d) a^(3)b^(5)

factorize 2x^(2) - 5xy + 3y^(2) , and use your result to factorize 2(3a-b)^(2) - 5(3a-b)(2a-b) + 3(2a-b)^(2) . The factors are

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

Factorize the following expressions (2a+3b)^2+2(2a+3b)(2a-3b)+(2a-3b)^2
