WebSince this is a quadratic, we know it’s factorable into (x-4) and another factor. (x-4) (ax+b)=2x^2-kx-12 We can find the value of a easily by seeing that x*ax=2x^2, so a=2. And similarly, -4b =12, so b=3. (x-4) (2x-3)=2x^2-kx-12 FOIL out the factors and you get: (x-4) (2x-3) = 2x^2–5x-12 Therefore, k=5.
