Question

The number of zeros of x²+3x+2

Answer 1

2.. because the gegree of the polynomial is 2.

it is a quadratic polynomial..

Answer 2

• If the polynomial have power 2 then it has two zeroes , and the zeroes of polynomial depend upon the power of the polynomial .

Question

• The number of zeros of x²+3x+2. $\sf$

Solution

$\sf » \: x² + 3x + 2$ ( By splitting method )

$\sf » \: x² + ( 2 + 1 )x + 2$

$\sf »\: x² + 2x + 1x + 2$

$\sf » \:x ( x + 2 ) + 1 ( x + 2 )$

$\sf »\: ( x + 2 ) ( x + 1 )$

Hence

• ( x + 2 ) ( x + 1 ) are the two zeroes of the polynomial.
