Using factor theorem,factorize each of the following polynomials: 2x^(4)-7x^(3)-13x^(2)+63x-45

Fractorise: 20a ^(2) - 45 b ^(2)

factorize : 20x^2-45

Factorize the following expressions 20x^2-45

When the origin is shifted to (-2,-3) and the axes are rotated through an angle 45^(0) , find the transformed equation of 2x^(2)+4xy-5y^(2)+20x-22y-14 = 0 .

The HCF and LCM of the polynomials p(x) and q(x) are (x^(2)+2x)(x^(2)-20x+91) and 2x^(2)(x^(2)-2x-143)(x^(2)-5x-14). If p(x) is x(x-13)(x-7)(x^(2)+13x+22), then q(x) is

If y=x^(3)-12x^(2)+45x-13 , then values of x at which rate of change of y with respect to x is zero are
