Step-by-step explanation:
1. 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. In you case, the trinomial must be written as
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.
In your case, coefficients 2, 5 and 3 do not have common factors, so go to the next step.
3. Multiply the leading coefficient and the constant, that is multiply the first and last numbers together:
4. List all of the factors from step 3 and decide which combination of numbers will combine to get the number next to x:
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:
6. Rewrite the original problem with four terms by splitting the middle term into the two numbers chosen in step 5:
7. Now that the problem is written with four terms, you can factor by grouping:
Answer:
It is in simplest form

Answer:
Step-by-step explanation:
Do substitution by first writing an equation 15c + 29a=175 when you get your answer either substitute it in your other equation which would be 21c+27a=177, if you found c(Children) in your first equation substitute it in 21 by multipying if you found a do the same thing.
Answer:
It would've been more difficult to solve and doing it as shown in EX:2 it's a way easier method to use and remember.
I cannot do turning points.
Also, if this is from a test, it can be removed.
But here is a graph of the function.
