Question

For what value of ‘s’, 3 is a zero of the polynomial 2x2 + x + (s – 3).

Answer 1

Answer:

Step-by-step explanation:

Put x=3 and equate polynomial to 0

Therefore,

2(3)² +3 + (s-3)=0

18+3-3+s=0

s=-18

Answer 2

P(x)=2x²+x+(s-3)

P(3)=2(3)²+3+s-3

=2x9+s+0=18+s

Now, here given that p(3)=0

18+s=0=>s=-18

Therefore,s=-18
