<em><u>To factor this trinomial, you must split the middle term (-12x) into two terms that can be added to get -12x, and multiplied to get 35:</u></em>
<em><u /></em> - 12x + 35
-7x - 5x + 35
<em><u>Group:</u></em>
( -7x) (-5x + 35)

Caroline traveled 544 miles on 16 gallons. We do some simple math and divide 544/16 and receive 34 miles/gallon. All we do now is multiply 34 * 9 and we receive 306 gallons.
