7.4 Dividing polynomials

$\frac{\text{28}{k}^{3}p-\text{42}{\text{kp}}^2+\text{56}{\text{kp}}^3}{\text{14}\text{kp}}=$

$\frac{x^2-\text{12}x-\text{45}}{x+3}=$

• A

  $\frac{{\mathrm{2y}}^2+y-\text{16}}{y-3}=$

• B

  Test your answer by choosing a number for $y$ and seeing if you get the same answer.

$\frac{{\mathrm{2h}}^3-{\mathrm{5h}}^2+\text{22}h+\text{51}}{\mathrm{2h}+3}=$

$\frac{{\mathrm{2x}}^3-{\mathrm{4x}}^2+\mathrm{6x}-\text{15}}{x^2+3}=$

$\frac{x^3-{\mathrm{4x}}^2}{x-4}=$

• A

  $\frac{x^3-\text{27}}{x-3}=$

• B

  Test your answer by multiplying back.

After dividing two polynomials, I get the answer $r^2–6r+9–\frac{1}{r-3}$ . What two polynomials did I divide?
