Question

if 3 is zero of polynomial p(x)=2xsquare-3x+2a​

Answer 1

Answer:

3 is zero of polynomial

then, x=3

p(3)=2(3)*2-3(3)+2a

=18-9+2a

=9+2a

a=-4.5

Answer 2

Step-by-step explanation:

condition : 3 is 0 of polynomial .

then ,

p(x) becomes : p(3)

so,

$2 {(3)}^{2} - 3 \times 3 + 2a \\ \\18 - 9 + 2a \\ \\ = 9 + 2a$

thus it's not
