Hi Guys!
Help me !! please!
Zeros & Remainder Theorem
1.
What is the remainder when 2x2 + 6x + 3 is divided by (x + 3)?
A) 39
B) 3
C) 1
D) 0

Answer 1

Using the remainder theorem, if you divide f(x) by x-r, then that's the same as computing f(r)


In this case, r = -3

So f(r) = f(-3) = 2(-3)^2+6(-3)+3 = 2(9)+6(-3)+3 = 18-18+3 = 3


This means that f(-3) = 3


So the remainder of dividing 2x2 + 6x + 3 by (x + 3) is 3


So the answer is choice B
