Question 1153934
<pre>
No, it is not.

(8x+3)(3x-2) = {{{ 24x^2 - 16x + 9x - 6 = highlight(24x^2-7x-6) }}}


Recall (c+d)*a = ac+ad by the distributive property of multiplication.
Now if a=e+f you get  

(c+d)(e+f) = (c+d)*a = ca + da = c(e+f) + d(e+f) = ce + cf + de + df  (some use the mnemonic FOIL to remember this: First, Outer, Inner, and Last.)
