Question

How do you factor trinomials?
Example:

Answer 1

Find two numbers that multiply to 5 AND add to 6

Answer 2

@jim_thompson5910 What two numbers multiply to 5 and add to 6?

Answer 3

any ideas of what they could be?

Answer 4

OH , 1 & 5? Haha. @jim_thompson5910 Blonde moment.

Answer 5

you got it

Answer 6

so n^2+6n + 5 factors to (n+1)(n+5)

Answer 7

So then it's just (n+1)(n+5) correct? @jim_thompson5910 Thanks so much!

Answer 8

you nailed it

Answer 9

that's all there is to it

Answer 10

That's easier than I thought. I appreciate it!

Answer 11

yw

Answer 12

What about if its an equation like n2+7n+10? Nothing computes to those?

Answer 13

list out the factors of 10

Answer 14

1,2,5,10?

Answer 15

so we have 1+10 = 11 .... so 1 and 10 aren't it

2+5 = 7 ... that's it, we found it, so we're done

notice how 1*10 = 10 and 2*5 = 10

Oh! Awesome thanks! :) @jim_thompson5910
