Note from the author:

Learn how to use the Formative platform to create scaffolded math assignments & activities - going deeper than just glorified online worksheets or multiple choice questions. Doing a bit of scaffolding work on the front end will reveal whether students actually understand the math processes and relationships!

0.5

Read #764, and part (a).
One of the factors of 2x^{2}+5x-12 is (2x-3). We need to determine the other binomial factor. Start by thinking this way: What can be multiplied by 2x to yield 2x^2?

0.5

We now know that our binomial must look like this:
(x + \underline{\hspace{5mm}} )
What number must go in the blank so that when it is multiplied by the -3 in the first factor (2x-3), the result will be -12?

0.5

Based on your responses to #1 and #2, what is the missing factor in #764(a)?

0.5

Type out the entire factorization statement from #764(a). It should look like:
2x^{2}+5x-12=(2x-3)(answer to #3).

Using the same ideas from #1 and #2 above, what must be the missing factor in #764(b)?
