To factor \[x^2+11x+10 \] we have to focus on the middle term and the last term so our last term is 10, and we have to list all possibilities of multiplication of 10 so our choices would be 1 x 10 = 10 2 x 5 = 10 then based on the middle term we use addition and only one pair of numbers work

ok

so what's 1+10? what's 2+5 ?

prime?
UsukiDoll
  • UsukiDoll
ah! We found our 11 because 10+1 = 11 10 x 1 = 10 so since we have found or numbers we can factor
anonymous
  • anonymous
ok
UsukiDoll
  • UsukiDoll
since your quadratic equation is all positive signs, we don't have to worry about sign combinations
UsukiDoll
  • UsukiDoll
so we have (x+ ?)(x + ? ) fill in those ? using the information I've typed earlier

x+11
UsukiDoll
  • UsukiDoll
close xD "We found our 11 because 10+1 = 11"
anonymous
  • anonymous
x+10?
UsukiDoll
  • UsukiDoll
no.. remember those 2 digital 10 and 1 that produced 11? write those down (x+?)(x+?)
UsukiDoll
  • UsukiDoll
wut did I just type .. it's 2 numbers 10 and 1 =_=

5+2
UsukiDoll
  • UsukiDoll
no now we're going backwards 5+2 is 7 and it doesn't match the middle term which is 11 so we throw that combination out
anonymous
  • anonymous
then i don't know
UsukiDoll
  • UsukiDoll
:/ we found our combination 10 x 1 = 10 which matches the last term 10 + 1 = 11 matches the middle term what numbers did I just use to make 10 and 11 ?
anonymous
  • anonymous
1
UsukiDoll
  • UsukiDoll
yeah that was one of the numbers. (x+1)(x+?) what was the other number?
anonymous
  • anonymous
was it 2?
UsukiDoll
  • UsukiDoll
no
anonymous
  • anonymous
and 10
UsukiDoll
  • UsukiDoll
yes! (x+1)(x+10)
anonymous
  • anonymous
thanks
UsukiDoll
  • UsukiDoll
and you can check by using the FOIL method (x+1)(x+10) = x^2+10x+x+10 =x^2+11x+10
anonymous
  • anonymous
so is that the final answer?
UsukiDoll
  • UsukiDoll
yeah
