For this case we have the following polynomials: [tex]f (x) = 21x ^ 2 + 13x - 20
g (x) = -3x - 4[/tex] To divide the polynomials we must follow the following steps: 1) Same base, the exponents are added. 2) Only terms that have the same exponent can be added or subtracted. 3) If the remainder is zero, the division is exact. Answer: [tex]f (x) / g (x) = -7x + 5
