Simplify: a2-a-12 a2-16
I find your lack of operators to be very disturbing.
As if a billion polynomials were all factoring at once, and were suddenly silenced...
Do you possibly mean..."Please will somebody help me simplify a2-a-12a2-16?"
Which textbook are you using?
"Tom Sawyer's Guide To Fence Painting, Homework and Other Onerous Tasks"
LOL... "This is too much fun... you cant do this with me! I want the satisfaction of getting the answer ALL to myself". :P
Its got complex roots.
But no apostrophes? :-D
I would but I don't understand what you mean by "12 a2". do you mean 12 x a^2???
