ab(x^(2)+y^(2))-xy(a^(2)+b^(2))

The HCF of x^(2) - xy - 2y^(2) and 2x^(2) - xy - y^(2) is

Fractorise: ab (x ^(2) + y^(2) ) + xy (a^(2) + b ^(2)).

Factorise: ab (x ^(2) + y ^(2)) - xy (a ^(2) + b ^(2))

Factorise : (vi) ab (x^(2) + y^(2) ) - xy (a^(2) + b^(2) )

If cos^(-1) . x/a - sin^(-1). y/b = theta (a , b , ne 0) , then the maximum value of b^(2) x^(2) + a^(2) y^(2) + 2ab xy sin theta equals

If cos^(-1) . x/a - sin^(-1). y/b = theta (a , b , ne 0) , then the maximum value of b^(2) x^(2) + a^(2) y^(2) + 2ab xy sin theta equals

Resolve each of the following quadratic trinomials into factors: 6x^(2)-13xy+2y^(2)(2)14x^(2)+11xy-15y^(2)6a^(2)+17ab-3b^(2)(4)36a^(2)+12abc-15b^(2)c^(2)

If theta is eliminated from the equations x=a cos(theta-alpha) and y=b cos(theta-beta) , then x^(2)/a^(2) + y^(2)/b^(2) -(2xy)/(ab) cos(alpha-beta) is equal to:
