Answer:

2x + 9 with a remainder of 45.

Step-by-step explanation:

If the divisor is x-5, use the divisor 5 in synthetic div.

Taking the coefficients 2, -1 and 4 from the dividend, we get:

    ------------------

5  /    2    -1    4

              10   45  

    --------------------

       2       9   49

This tells us that the quotient is 2x + 9 and that the remainder is 49.
