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

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

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

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

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