Find the zero of the polynomial:$P(x)=x- 5x+6$

Academic Mathematics NCERT Class 8

Given: $P(x)=x- 5x+6$

To do: Find zero of the polynomial

Solution:

Your question is "The zero of the polynomial $P(x)=x^2- 5x+6$

$x^2-5x+6=0$

$x^2-3x-2x+6=0$

$x(x-3)-2(x-3)=0$

$(x-3)(x-2)=0$

$x-3=0 or x-2=0$

$x=3 \ or \ x=2$

Zeroes of the polynomial P(x) are 3 and 2.
