33*x^(2)-(a+b)x+ab

Which among the following is the correct value of (x+a)(x+b) a) x^(2)+abx+ab (b) x^(2)-(a+b)x+ab(c)x^(2)+(a+b)x+ab (d) x^(2)+(a-b)x+ab

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

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

If a

Find the derivative of x^2 - (a + b)x + ab for some constants a and b .

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

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

Solve for x and y:x^(2)-y^(2)=xy-ab,(x+y)(ax+by)=2ab(a+b)
