Factor completely 2x^2 + 2x − 24.
first simplify it by taking out a common factor
So 2, then?
yes divide the whole expression by 2 so it will be easier to factor
Alright, so I got x^2 + x - 12
looks good now you look for two numbers that when multiplied together give you -12 but when added together give you 1
1 is the coefficient for x
Ah, okay. Give me a minute
4 and -3?
yep now you put it into the blanks here |dw:1434582773871:dw|
So will there always be a set of parenthesis with a + and the other with a -?
no, only in this case since there is NEGATIVE 3 and POSITIVE 4
Oh, okay. Thank you so much for walking me through this!
no problem :)
