How is factoring a trinomial different than factoring a number?

Step 7 :Now that the problem is written with four terms, you can factor by grouping.

Step-by-step explanation:

Make sure that the trinomial is written in the correct order; the trinomial must be written in descending order from highest power to lowest power.

Step 2 :Decide if the three terms have anything in common, called the greatest common factor or GCF. If so, factor out the GCF. Do not forget to include the GCF as part of your final answer.

Step 3 :Multiply the leading coefficient and the constant, that is multiply the first and last numbers together.

Step 4 :List all of the factors from Step 3 and decide which combination of numbers will combine to get the number next to x.

Step 5 :After choosing the correct pair of numbers, you must give each number a sign so that when they are combined they will equal the number next to x and also multiply to equal the number found in Step 3.

Step 6 :Rewrite the original problem with four terms by splitting the middle term into the two numbers chosen in step 5.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
