Use the grouping method to factor this polynomial x ^ 3 + 2x ^ 2 + 7x + 14

elena55 [62]

Answer:

B. ( $x^{2}$ +7)(x+2)

Step-by-step explanation:

The greates common factor between 7 and 14 is 7 so you know that one of the terms is going to be 7....but what times 7 equals 14...2

So we know that in one set of parentheses its going to be (something +2) and in another (something +7)

Well if we know that one is going to be 2, how do we go from 2 to 2 $x^{2}$ .....2 times $x^{2}$ equals $2x^{2}$

So now we know that one set of parentheses is going to be (something + 2) times ( $x^{2}$ +7)

So lastly, we have to find out how to get $x^{3}$ but since we already have a $x^{2}$ in the second set of parentheses all we have to do is put a x in the first set because x times $x^{2} = x^{3}$

Hope this helps!

Michael worked 10 hours and earned $175 constructing fencing. If he averages 8 yards per hour, how much is he paid for each yard

ryzh [129]

So, $175 is the total of 10 hours of his work. We have to divide the 175 to 10 so that we can get his hourly wage. 175 divided by 10 is 17.5. Multiply the 17.5 to 8 hours, its $140
