Use synthetic division to find the result when x^4 + 3x^2 + 23x – 17 is divided by x – 3. If there is a remainder, express the result in the form q(x) + r(x)/b(x)

For question 24 the In this sum, the greater number is 9, however, 9 doesn't have a negative sign, which means that the answer to this sum should be a positive 3 not negative  

And for question 25 the In this sum, we should use a known rule, a negative number plus a negative number is a negative one, which means that we should be adding -10 and -10 to get a -20.
