Question

Show that √2 is a zero of the polynomial p(x) = 7x2 − 2√8 x − 6.

Answer 1

Answer:

Step-by-step explanation:

p(x)=

is a factor of x+3

by factor theorem if p(-3)=0 then x+3 is a factor of P(x)

sot let's check it

p(3)=

=81-27-63+3+6

=90-90

=0

hence we proved that x+3 is a factor of given expression..
