Question

Need help with dividing polynomials

Answer 1

what's the rational eqn?

Answer 2

helooo?

Answer 3

4xsquared+x-3/x+1

Answer 4

that yields
\[(x+1)(4x-3)/(x+1)\]

Which you can see gives you 4x-3

Answer 5

Thank you. My son is having trouble understanding how to process the top of the problem.

Answer 6

You have to factor the polynomial in the numerator \[4x ^{2}+x-3\]

the denominator is a hint that one of the factors of the polynomial is x+1
you know that something times x+1 is \[4x ^{2}+x-3\]

so by trial and error with FOIL you can see that the other factor is 4x-3
