Challenges from page 20...

Hey, some of those are tough! I'm glad you made it that far. Well done.

The key to solving a question like h) or i)is to pretend you're factoring it. Using h) as an example:

• Begin by multiplying 4 and 3 to get 12.
• Ask yourself what factors of 12 add to equal 'k'.
• Stop and think, "If 'k' can be equal to anything, then it could be equal to any sum of the factors of 12."
• List the sums of the factors of 12 as your answer.

One answer could be 4x^2 + 13x +3 since 1 and 12 multiply to 12, but add to 13.

Hope that helped. If not ask me to clairify and I'll post a video explaining it more fully.

Thanks for the question. Have a great weekend.
