Polynomial Division (3 of 3: A useful shortcut - synthetic division)

[@vateoff]

u js hv to substitute the zero to the equation and u get the remainer if it gives a remainder its called remainder theorem f(x) = g(x)(x+2) + Remainder f(-2) = g(-2)(-2+2) + Remainder f(-2) = Remainder

How to find the deviser if not given

[@homeboi808]

You can’t do that unless you also have the quotient (answer).

[@muhammadayman2323]

Perfect 👌

[@Felipe.Taboada.]

That's Ruffini's rule

[@Diametric_]

does this work if the divisor isn't monic?

[@danielchua7627]

you could just factor the divisor? so if the divisor was (3x-2), you could change it to 3(x-2/3). So, you would do synthetic division using 2/3 as the zero of the divisor and then divide the whole thing by 3 at the end.

Daniel Chua Thanks, I hadn't thought about that

What does he have tucked in the side of his pants?

[@vbossnova6479]

A radio for school teachers or the bulk of the microphone. I think

[@whenthethebeansstrikeback6728]

It's a radio for communication

[@carultch]

It's the transmitter for the wireless microphone. So that his sound quality on the video is decent.

imagine having 5 minutes left a a COUPLE of questions..

[@thatomofolo452]

that's the truth though

[@NunuBot]

What if u r diving a third degree polynomial by a second degree polynomial? what do you do with the "zero" part?

[@tifnatandmat]

He said it's only for a linear divisor

[@unoriginalusernameno999]

There are two zeroes for a quadratic polynomial. A quadratic polynomial is of the form ax^2+bx+c. To find either of the x values you just use this--- x=(-b(+or-)sqrt(b^2-4ac))/2a and then you use the x

Ruffini!
