Answer:
ab + b²-ac-bc
b(a+b) -c(a+b)
(a+b) (b-c)
Step-by-step explanation:
You're told there is a 10th degree polynomial. There are four roots of multiplicity 1 and one of multiplicity 2 (a double root).
Anytime there is a root of multiplicity 1 of a polynomial, its graph crosses the x-axis at that root. Anytime there is one of multiplicity 2, it means that we count the root twice and the graph has a tangency point.
The degree of a polynomial tells you how how many roots it has. Ours is degree 10, so it has ten roots. We have the four roots of multiplicity 1 and the one of multiplicity two, for a total of 6. (four and two).
So there are six real roots.
The rest of the roots are imaginary and non-real, and 10 - 6 = 4. So there are four imaginary roots.
Thus choice C is best.

Answer:
to calculate a 18 percent tip on a $105 bill.
What should I tip on 105 dollars? How much is the tip for $105?
Tip $18.90
Total $123.90
Step-by-step explanation:
Put the percentage in decimal form (0.18) then multiply the cost by this number. 26.50 * 0.18 = 4.77. So your tip is $4.77.
