Hey what do you think we do first
What number can go into both 50,35,5?
you there @Puppylover100
5
Ok 5 do you think we can factor anything else out like variables ?
Well there is a^2 b^5 a^4 b^3 a^3 b^4 the two most common numbers are 3 and 4 2 can go into four ut not 5 or 3
so from looking at the answer choices, what do you think th answer is?
D
D??? do you know how to factor?
Why wouldn't be D? If you muliply everything by 5 you would get the original problem
No we have to divide
ok 5 goes into both correct? So we divide 5 by the 50,35,5
5 goes into 50 ten times, 35 seven times, and 5 once
|dw:1448727739499:dw|
a and b goes into all 3 terms so we find the smallest of both A and B so we have a2 and b3 and we subtract it from all 3 terms
ok
so 50/5=10 so we subtract 2-2=0 5-3=2
so what do we get
10b^2
correct because 2-2=0 so a cancels out :D how about the next term
7a^2
how about the next
ab
So the answer is?
10b^2-7a^2+ab
you forgot the something in the beginning
5(10b^2-7a^2+ab)
you forgot the variables
5a^2b^3(10b^2-7a^2+ab)
Correct :D
Thank you SO much
Anytime
