A polynomial is two or more monomial numbers that are linked together in an equation by an addition sign (+), subtraction sign (-) or a multiplication sign (x). In this quiz, we will be dealing with dividing a polynomial by a monomial - a number that stands on its own.

Let’s look at the following example of a polynomial divided by a monomial.

1.

(50*x*^{6} + 30*x*^{5} - 20*x*) ÷ (10*x*)

5*x*^{5} + 3*x*^{4} - 2*x*^{2}

5*x*^{5} + 3*x*^{4} - 2*x*

5*x*^{5} + 3*x*^{4} + 2

5*x*^{5} + 3*x*^{4} - 2

2.

(28*x*^{6} + 21*x*^{3} + 14*x*) ÷ (7*x*)

4*x*^{6} + 3*x*^{3} + 2*x*

4*x*^{5} + 3*x*^{2} + 2

4*x*^{5} + 3*x* + 2

4*x* + 3*x*^{2} + 2*x*

(28*x*^{6} + 21*x*^{3} + 14*x*) ÷ (7*x*)

28*x*^{6} ÷ 7*x* = 4*x*^{5}

21*x*^{3} ÷ 7*x* = 3*x*^{2}

14*x* ÷ 7*x* = 2

__Solution__: 4*x*^{5} + 3*x*^{2} + 2

Answer (b) is the correct solution. (Did you remember to subtract your exponents?)

3.

(45*x*^{5} + 35*x*^{3}) ÷ (-5*x*)

(-9*x*^{6}) + (-7*x*^{4})

9*x*^{6} + 7*x*^{4}

9*x*^{4} + 7*x*^{2}

(-9*x*^{4}) + (-7*x*^{2})

(45*x*^{5} + 35*x*^{3}) ÷ (-5*x*)

45*x*^{5} ÷ (-5*x*) = -9*x*^{4}

35*x*^{3} ÷ (-5*x*) = -7*x*^{2}

__Solution__: (-9*x*^{4}) + (-7*x*^{2})

*(In order to not confuse anyone between the divide symbol and the negative value of 5, parentheses are placed around the negative value monomial.)*

Answer (d) is the correct solution. (Did you remember to subtract your exponents?)

Answer (d) is the correct solution. (Did you remember to subtract your exponents?)

4.

(96*x*^{2} - 36*x*^{2}) ÷ (12*x*)

8*x*^{3} - 3*x*^{3} = 5*x*^{3}

8*x* + 3*x* = 11*x*

8*x* - 3*x* = 5*x*

8*x*^{3} + 3*x*^{3} = 11*x*^{3}

(96*x*^{2} - 36*x*^{2}) ÷ (12*x*)

96*x*^{2} ÷ 12*x* = 8*x*

-36*x*^{2} ÷ 12*x* = -3*x*

__Solution__: 8*x* - 3*x* = 5*x*

Answer (c) is the correct solution. (Did you remember to subtract your exponents?) In addition, this problem has a final answer of 5*x* as 8*x* and 3*x* are “like” numbers

Answer (c) is the correct solution. (Did you remember to subtract your exponents?) In addition, this problem has a final answer of 5

5.

4*x*^{2} + 3*x*^{2} + 2

4*x*^{2} + 3*x*^{2} + 2*x*

4*x*^{2} + 3*x* + 2

4*x* + 3*x* + 2*x*

(24*x*^{3} + 18*x*^{2} + 12*x*) ÷ (6*x*)

24*x*^{3} ÷ 6*x* = 4*x*^{2}

18*x*^{2} ÷ 6*x* = 3*x*

12*x* ÷ 6*x* = 2

__Solution__: 4*x*^{2} + 3*x* + 2

Answer (c) is the correct solution. (Did you remember to subtract your exponents?)

(57*x*^{6} + 111*x*^{5} - 15*x*^{4}) ÷ (3*x*^{4})

19*x*^{2} + 37*x* + 5

19*x*^{2} + 37*x* - 5*x*

19*x*^{2} + 37*x* - 5

19*x*^{2} + 37*x* + 5*x*

(57*x*^{6} + 111*x*^{5} - 15*x*^{4}) ÷ (3*x*^{4})

57*x*^{6} ÷ 3*x*^{4} = 19*x*^{2}

111*x*^{5} ÷ 3*x*^{4} = 37*x*

-15*x*^{4} ÷ 3*x*^{4} = -5

(-31*x*^{6}) + (-14*x*^{3})

31*x*^{6} + 14*x*^{3}

(31*x*^{6}) - (14*x*^{3})

(-31*x*^{10}) + (-14*x*^{7})

(62*x*^{8} + 28*x*^{5}) ÷ (-2*x*^{2})

62*x*^{8} ÷ (-2*x*^{2}) = -31*x*^{6}
