you just apply it in reverse
for example
3(x^2 + 3x - 1) = 3x^2 + 9x - 3
the reverse of distribution is factoring:
3(x^2 + 3x - 1)

a(b+c)=ab+ac
using the symmetric property of equality ( if a=b then b=a )
ab+ac= a(b+c)

Yeah but i still dont get it
OpenStudy (anonymous):
By factor does it mean turn it into a factored notation or whatever its called?

4( 90 + 12) = 4*90 + 4*12

Im in 7th grade by the way
OpenStudy (skullpatrol):
4( 90 + 12) = 4*90 + 4*12 = 360 + 48
OpenStudy (skullpatrol):
a(b+c)=ab+ac

Ok i get that but its putting it like this 24r-32rx^2
OpenStudy (skullpatrol):
What is the common factor?

X^2 means exponent two by the way
OpenStudy (anonymous):
Thats what i dont get
OpenStudy (skullpatrol):
When two or more numbers are multiplied each of the numbers is a "factor" of the product.
OpenStudy (skullpatrol):
A "common" factor is what is common to the numbers.

Heres another one 15-35y would 5 be the common factor

yes
OpenStudy (skullpatrol):
5(3-7y)
OpenStudy (anonymous):
So its 5 x15 - 5 x35y?
OpenStudy (anonymous):
Oooooooooooohhhh
OpenStudy (anonymous):
Ok now i get it
