Question 1131329
<pre>Same as: Quadratic_Equations/1131330: 
Again, you don't need to FOIL the BINOMIALS.
Again, this is a DIFFERENCE of TWO SQUARES <======> {{{matrix(1,3, a^2 - b^2, "=", (a - b)(a + b))}}}
The same concept applies!!
Correct answer: {{{highlight_green((- 4m - 1)(2m - 1)(8m^2 + 2m - 7))}}}
