Fill `..........=x^2+(a+b)x+ab`

Fill in the blanks. (1) -2a^3b is a........ (2) (a^2-2b^2) is a ....... (3) (a+2b-3c) is a .......... (4) In -5ab , the coefficient of a is ...... (5) In x^2+2x-5 ,the........term is -5

x^(2)+2ab=(2a+b)x

Fractorise: x ^(2) - x (a + 2b) + 2ab

Important Identitiy (x+a)(x+b)=x^(2)+(a+b)x+ab

factorize : x^2-(a+b)x+ab

Resolve (x-b)/(x^(2)+(a+b)x+ab) into partical fractions.

If a

Factorise : abx^2+a^2x+b^2x +ab
