If x (2 3)+y(-1 1)=(10 5) find xand y

prove that if the side of a triangle is extended then the exterior angle is equal to sum of its remote interior angles

Alpha , beta are the roots of x^2+x +1=0 then equation whose roots are alpha^19, beta^16.

Two pairs of straight lines y^2+xy-12x^2=0, and ax^2+2hxy +by^2 =0 have one line in common then

What is 0 to the power of 0 

Proof

Divide 32 into four parts which are in AP, such that the ratio of product of extremes to the
product of means is 7:15.
