WHAT?
Mike - you have been so helpful and patient, but I am completely lost now.
Let me see if I can explain it back to you in words I understand
After finding the 2 numbers (-64, 9) I THEN have to factor the existing numbers down to multiply to those 2 numbers?
Ok, stuck again
24x^2 - 55x - 24
product of first and last coefficients (24(-24)= -576). Factors of -576 that ADD to middle coefficient (-55x) are -64, 9
However, if I check
(24x -64)(x+9)
24x^2 + 216x - 64x + 576
WHAT AM I DOING WRONG?
Understood - but
"The commutative law of multiplication says that ab=ba, so yes, it could be (2x⋯)(x⋯) or (x⋯)(2x⋯)...I should have said one would have to to (2x⋯) and the other (x⋯)."
What is the rule that makes the placement of the (2x...)(x...) vs (x...)(2x...)? Or is it just that you have...
Mostly - here's where I don't have clarity
"Now, for the quadratic factor, we see the leading coefficient (2) is prime, and so we know the factorization will take the following form:
6x2+39x−21=3(2x2+13x−7)=3(2x⋯)(x⋯)
Because the coefficient (2) is prime it always holds the position in the...
I really hope someone here can help me - I'm sure that's not going to be difficult for most. :)
I'm helping a friend's daughter factoring trinomials. I can get to the correct answer, but usually thru a system of trial and error and not a defined set of rules in every instance. Example
6x^2...
