Use synthetic division to solve (2x^3+4x^2-35x+15) divided by (x-3) What is the quotient?
Salsk061 [2.6K]

Answer:


Step-by-step explanation:

The only thing you need to watch carefully is the divisor which in this case is   x - 3. The divisor, in synthetic division, is the number that will make the binomial go to 0.  

x - 3 =0

x = 3

So the divisor is 3.

3  ||  2    4    -35    15

             6     30    -15

======================

       2   10    -5      0

So the quotient is

2x^2 + 10x - 5 with no remainder
