Get the Math and the Points! Common Core Algebra I Aug 2017 Regents #3

Aug 2017 CC Alg I 3

This can be easily solved by checking the answers:  we will need a + and – to create a – so answers (1) and (2) are gone.
Look at (4): If we multiply (24.5x)(24.5x) we definitely get more than 49x^2 so finding this answer is easy.

Students can also put 49x^2 – 36 into Y1 on the TI-84 and then try each of the answers into Y2 and see which creates the same graph and/or table.

That’s it, 2 more points on the Regents!!
