(v)x^(2)-(2a+b)x+2ab

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

Find the zeroes of the quadratic polynomials and verify the relationship between the zeroes and the coefficients. x2 - (2a + b) x + 2ab

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

If (x+1)/(x-1)=(a)/(b) and (1-y)/(1+y)=(b)/(a), then the value of (x-y)/(1+xy) is (2ab)/(a^(2)-b^(2)) (b) (a^(2)-b^(2))/(2ab) (c) (a^(2)+b^(2))/(2ab) (d) (a^(2)-b^(2)backslash)/(ab)

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

The square root of x^(b^(2))x^(b^(2)+2ab)x^(a^(2)-b^(2)) is
