4x2+7x+4x+7
4x2+11x+7
the formula x=[-b+-\sqrt{b ^{2}-4ac}/2a\]
a=4,b=11,c=7
put in the formula

O.o Um i got it already but thanks. I haven't learned it like that but thanks anyway (: I appreciate it (:

phi · Answer

study multiplied it out to get the answer.  Then gave the quadratic formula, which allows you to "go the other way"  start with the quadratic and find (x+1)(4x+7).  Something tells me you are not learning that yet.

@phi i learned it but when i was looking back, like i didn't understand what I was doing, so I have to review. And I thought i was doing it wrong so i wanted to check.
@studyisbest Thank you (:
