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
thx
Hello,
1. expand the brackets at the LHS of your equation.
2. collect like terms
You'll get:
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!
