Question

can someone please please help me ?

Answer 1

with?

Answer 2

Part 1:
In your own words, explain how a trinomial of the form 2x2 + 13x + 15 can be turned into a four term polynomial suitable for factoring by grouping. Use complete sentences.

Part 2:
If you were an Algebra 1 instructor and were creating a test on factoring trinomials of the form ax2 + bx + c, what do you think would be the easiest way to create a trinomial that can be factored? Provide one unique example.

Answer 3

Part:

Try to make the factors using 10 and 3

10 + 3 = 13..

Answer 4

can you guys help me ? please

Answer 5

Someone else would have to confirm this because I'm not entirely sure, but for part 1, to turn it into a four term polynomial, I think we can just multiply the polynomial by x. So, you would do x(2x^2 + 13x+15) and would get 2x^3 + 13x^2 + 15x + 0 which is technically a four term polynomial.

Answer 6

okay thankyou

Answer 7

Hold on, I think that's a bit off though. Wait a min.

Answer 8

Okay so the first step is actually to find factors of 30 that add up to 13(the middle term) so as @waterineyes was saying (10+3)

Answer 9

Then you can rewrite the original expression as 2x^2 + 10x + 3x + 15 which is a four term polynomial.

Answer 10

Let me know what questions you have on the first part, then I'll help you with the second.
