Question

Using long division method find out whether g(x)=1+x is factor
of p(x)=x+3x2
-1. Also verify the division rule. [3]

Answer 1

Step-by-step explanation:

-by-step explanation:

Given: p(x) = x + 3x² - 1

g(x) = 1 + x

We have to divide p(x) by g(x).

First, we rewrite the polynomial.

p(x) = 3x² + x - 1

g(x) = x + 1

Long Division is attached in pic.

Quotient = 3x - 2

Remainder = 1

Answer 2

Answer:

put the value of x in p(x)

Step-by-step explanation:

p(-1) = 1+3×2 =7
