dividing polynomials is just like long division… hang on a minute… i’ll work them out

1)U

write:((12m^2n^5)(m^2-25))/((m+5)(3m^3n)

=((m-5)(m+5)(3m^2n)(4n^4))/((m+5)(3m^2n))

=((m-5)(4n^4))/(m+5)

2)e

3)t

4)i

5)d

6)w

7)s

8)l

9)a

first thing you need to note is that all of these “division” problems are really just multiplication problems… flip the second term over and multiply…

also note that most of these are simple (factorable) polynomials…

factor the individual terms into their simplest form before doing anything else… this will make it very easy to see what cancels…

long branch of polynomials is quite comparable to long branch of numbers. it quite works precisely like long branch of numbers could if digits ought to circulate from minus infinity to infinity. With numbers you’re able to start up on the leftmost digit – the optimal potential of 10 – and artwork your thank you to the superb. With polynomials, start up on the optimal potential of the variable and artwork your thank you to the superb. With numbers you’re able to divide this leftmost piece of the dividend by ability of the divisor to fill interior the 1st digit of the quotient. With polynomials, that’s analagous yet even much less complicated. To fill interior the 1st term of the quotient, you merely want the optimal potential interior the divisor. what proportion circumstances does 3t^2 circulate into 6t^4?. As with numbers, multiply out the divisor by ability of the recent piece of the quotient, and subtract. in case you have carried out it superb, the leftmost digit/term of the dividend will disappear. (3t^2+2t-4) * 2t^2 = 6t^4 + 4t^3 – 8t^2 (6t^4-5t^3-8t^2+15t-8) – (6t^4 + 4t^3 – 8t^2) = -9t^3 + 15t – 8 handle something because of the fact the recent dividend and repeat the technique, until eventually you attain the top of the quotient.

first 3 questions the answer is 1.H 2.E 3.W
