IF THE CURVE Y=AX2+BX PASSES THROUGH (-1,0) FIND Y=X IS THE TANGENT LINE AT X=1 THEN (a,b)

Dear girdhar

Y=AX²+BX

it passes through (-1,0)

so it will satisfies the given equation

0 = A -B

A=B

and dY/dX =2Ax + B

                     =2A +B

given dY/dX =1

             2A +B =1

             3A =1

A=1/3 =B
