start by finding the Greatest common factor of 8 and 36
How can i ?
well, can you list the factors of 8?
uh, not quite... the factors of 8 are: 1,2,4, and 8 and the factors of 36 are: 1,2,4,9,12, 18, and 36 so our GCF is 4, since this is the highest number they both have in common with me so far?
i Div 8 by 36 and i got 28. How did you get 4
uh, I'm not quite sure how you got 28... do you know what a factor is?
ok so you want me to do 8 Div 36
uh, well, it would be good to learn what a factor is before attempting these problems http://www.math.com/school/subject1/lessons/S1U3L1GL.html
How did you get 4
Thats what i don't understand ?
I don't mean "divide 8 by 36" , I meant to find the biggest number that goes into 8 and 36
Ok how can i know, the biggest number that goes by the two numbers.
start by listing the factors of 8 and 36
Ok i get it now
so it would be 4x
just 4, not 4x, we'll get to the x in a minute now, we factor out 4 giving us: 8x5 − 36x2 = 4(2x^5-9x^2)
now, the GCF of x^5 and x^2 is x^2, so we factor that out, giving us: 4x^2(2x^3-9) which is our answer
How you get 2
