Answer 2

you have to remember that you can only add or subtract like polynomials. (x²+4x+9) must be added to something to get (2x²-6x+14)

first look at the second degree terms. x² plus some number must equal 2x². x²+x² equals 2x².

now the first degree terms. 4x plus some number must equal -6x. 4x-10x equals -6x

finally look at the constants. 9 plus some number must equal 14. 9+5 equals 14.

so let's look at the numbers we found. (x²-10x+5). this is what r(x) is equal to.
