i do not get this

use division to determine whethe the binomial is a factor of f(x)

F(x)=x^3+20x-32; x-2

yes or no

• Algebra -

3 is a factor of 12 because 3 divides exactly into 12 leaving no remainder

similarly if x-2 is a factor of x^3+20x-32 then it must divided exactly into it leaving no remainder.

so...
divide x^3+20x-32 by x-2 and see what happens.

Are these right? xy - 3x - 8y + 24 (3x-y)-(8y+24) 8y+24 4x^2 + 20x + 5y +xy 36x+(5y+x) 36x-5y I don't think so it's right.Your question xy-3x-8y+24 is itself the answer.It cannot be further calculated bcause it doesn't have the terms
