given that (x^2-2x+3)(x^2+Kx-2) = x^4-15x^3+qx^2+px-6
find the values of K, p and q
iv tried n jst keep gettin lost
1. expand the brackets at the LHS of your equation.
2. collect like terms
Now compare this result with the coefficients at the RHS of the given equation:
This is a system of 3 linear equations which could be solved for k, p, q.
(For confirmation only: I've got k = -13, q = 27, p = -35) but you'd better check my calculations!
