I need help on this one algebra problem. I don't know how to do it and I need help. '14a(squared) - 15a + 4' can someone tell me the steps and all to factor this?
-
Just use the quadratic formula
-
Also the proper notation is 14a^2 - 15a + 4
-
You'd write all of the possible things out, obviously, Chris.
1-14
2-7
1-4
2-2
And then the trick I learned is something like this. This is an example.
(4z + 5)(4z - 5)
Here, you'd multiply the center numbers.
(4z + 5)(4z - 5) = Positive 20z
And then you'd multiply the other two numbers.
(4z + 5)(4z - 5) = Negative 20z
20z - 20z = 0 -
Or if you are intelligent
(-b(+-)sqrt(b^2-4ac))/2a -
That wasn't intended to sound so mean.
-
Wait when you write out the numbers then what
-
is not intelligent
ANYWAYS TO HELP THE IDIOT WHO IS IN THE SAME CLASS AS ME!!
chris why are you so silly
Apply it to that problem.
Possibilities: (1 or 2 - 1 or 2)(14 or 7 - 4 or 2)
( - )( - )
It's 2-7 and 1-4; You'd multiply the 7 and 1 and get 7, then the 4 and 2 and get 8. 7 + 8 = 15. -
( - )( - )
lol boobies -
Not sure which order, though. It should be one of these.
(2a - 1)(7a - 4)
(7a - 4)(2a - 1) -
lololololol
oh and chris, which problem is it? -
Order doesn't matter
-
It's the (7a - 4)(2a - 1)
-
oh wait, true
-
i still dont get it
