Question

verify that 2 is a zero of polyno miel x^3+4x^2-3x-18
​

Answer 1

Answer:

yes 2 is a zero of the polynomial

Step-by-step explanation:

given

f(x)=x³+4x²-3x-18

put x=2 in the eqn

u will get f(x) as 0

thank you

Answer 2

Step-by-step explanation:

If 2 is a zero, then it must satisfy the polynomial.

Then, f(2)=2

3

+4(2)

2

−3(2)−18=8+16−6−18

=24−24=0

Hence, 2 is a zero of the polynomial.
