Question

check whether (x-1)is a factor of 2x^2+3x+1

Answer 1

Let p(x)=2x^2+3x+1

If p(1) is 0 then x-1 is factor of p (x)

p (1)=2 (1)^2+3 (1)+1

=2+3+1

=6

so p (1) is not equal to 0 so x-1 not a factor of p (x)

Answer 2

Hi friend
--------------
Your answer
-------------------

TO CHECK WHETHER (X-1) IS A FACTOR OF (2X²+3X +1)

LET,
-------

P(X) = 2X²+3X+1

NOW,
--------

X - 1 = 0

X = 1

PUTTING , P(1)
---------------------

P(1) = 2 × (1)² + 3×1 +1
= 2×1 + 3 +1
= 2+4
= 6

SO,
-----
(X-1) IS NOT A FACTOR OF THE GIVEN POLYNOMIAL.

HOPE IT HELPS
