Use synthetic division to determine if x+2 is a factor of f(x)=5x2+13x+6

x+2 is a factor of

Step-by-step explanation:

To check: If (x+2) is a a factor of the polynomial

We need to check if x  = -2 is the FACTOR of the given polynomial.

⇒ To show:  f (-2)  =  0

Now

Since, f(-2) = 0

⇒  -2 is the ROOT of the Polynomial f(x).

⇒(x +2) is the factor of the given polynomial.

Hence, x+2 is a factor of

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21
