Question

find zero of the following polynomial p(x)=3x​

Answer 1

$\huge { \underline{ \underline{ \mathbb\red{{ANSWER}}}}}$

p(x) = 3x

x = 0

3 × 0 = 0

so, 0 is the zero of polynomial.

3x = 0

x = 0/3 = 0

Answer 2

Answer:

Here, p(x)=3x−2.

In order to find zero of p(x), we equate p(x) to 0,

i.e p(x)=0.

⇒3x−2=0⇒3x=2⇒x=

.

∴

3

2

is the zero of p(x).
