    a and c as maximum power of x and y is 1 in b there is x² term and in d x(x².... will turn it into x³ so it will be cubic not linear.

    y=x³-2x²+1 intersect y=x+a, emilimate y u get: x+a=x³-2x²+1 0=x³-2x²+x+1-a --(1) question say that the equation u get on intersection is y=x³-2x²+x+1+2solve them simultaneously and u get -a=+2 or a=-2 draw the line y=x-2(value of a is -2) so the x-coordinates of intersections are values of x.
