Factorize: `9(2a-b)^2-4(2a-b)-13`

Factorize: 9a^2-16 b^2

Factorize 9-a^2+2ab-b^2

Factorize a-b-a^2+b^2

Factorize: a^2+4b^2-4a b-4c^2

Factorize: a^4-2a^2b^2+b^4

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

factorize : 9a^2+3a-8b-64b^2

Factorize: a^(2)+4b^(2)-4ab-4c^(2)

Factorise: 4(2a - b+c) ^(2) - 9 ( a+b- c) ^(2)
