Answer:
(2x + y)(2x - y - 1)
Step-by-step explanation:
4x² - y² - 2x - y
4x² - y² is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
4x² - y²
= (2x)² - y²
= (2x - y)(2x + y)
expression is now
(2x - y)(2x + y) - (2x + y) ← factor out (2x + y) from each term
= (2x + y)(2x - y - 1)
6x10^3 :six times ten to the third power
25/50 * 100% is the expression that gives the percent of voters who voted from candidate b.
Candidate B. 25/50 = 0.50 * 100% = 50%
Candidate A. 15/50 = 0.30 * 100% = 30%
Did not vote (50-25-15)/50 = 10/50 = 0.20 * 100% = 20%
Voted Candidate A 15 30%
Voted Candidate B 25 50%
Did not vote <u> 10 </u> <u>20%</u>
Total number of students 50 100%
