Equivalent expressions

Question

Evaluate 27x to the second power + -42x + 12 in the equivalent expression that you wrote in problem 7 which was 3 times 9x to the second power + -14x + 4 for x equals to what do you notice about the value of the two expressions show your work I hope that you understand

Answer 1

The question is very poorly worded and should not refer to some other (numbered) problem.

 

I think that this could be the result of artificial, 'forced' pseudo-narrative being attempted by zealots of Common Core.

 

I believe that they're talking about 27x² - 42x + 12 which can be factored:

3(9x²- 14x + 4).

 

This is an example of a Factoring Rule: First isolate the greatest common monomial factor.

 

There is absolutely nothing in Common Core superior to this long-extant knowledge, and there need not be any fear about teaching the time-honored basics.
