Question

Verify Whether the following are roots of the polynomial equations indicated against them.

$x^2-5x+6=0;(x=2,3)$

Answer 1

putting values in equation $x=2$

$2^2-5\times 2+6=4-10+6=0$

for $x=3$

$3^2-5\times 3+6=9-15+6=0$

Thus the values of $x=2,3$ are the roots of the polynomial equation mentioned above.
