Question

determine whether -3 is a zero of the polynomial x²+5x+6

Answer 1

hey mate!

here is your answer:

If -3 is a zero than x^2+5x+6 should be equal to 0

x^2+5x+6=0

putting the vlaue of x as -3 in LHS

so, (-3)^2+5(-3)+6=9-15+6=15-15=0=RHS

as RHS=LHS so, -3is a zeto of x^2+5x+6

hope it helped ^_^

Answer 2

Answer:

Step-by-step explanation:

P(-3)= (-3)^2+5(-3)+6

=9 -15+6

=9-9

=0

Therefore it is the zero of the polynomial.
