There exists a polynomial f(x) and a constant k such that (x^2 - 2x - 5) f(x) = x^4 - 2x^3 + kx^2 What is k?
pweeez use latex
(x2−2x−5)∗f(x)=x4−2x3+kx2 well the x4 has no coeficient and both polynomials have the same amount of terms so that means f(x) is just x2. which means k is −5. at least i think so :P ¯\_(ツ)_/¯
x^2
x^2 -2x - 5 [ x^4 - 2x^3 + kx^2 ]
x^4 - 2x^3 - 5x^2

k + 5 must = 0
k = -5
