Question

is 2 is zero of polynomial ax2-2x then the vale of 'a' is

Answer 1

The value of a is 1

Step-by-step explanation:

if 2 is the zero of the polynomial

ax²-2x

then

ax²-2x =0

place the value of x = 2

then

ax²-2x =0

a(2)²-2(2) =0

4a -4 =0

4a =4

a = 1

hence , the value of a is 1

Answer 2

Answer:

Given:-2 is a zero of the polynomial ax²-2x.

or, P(x)=ax²-2x=0

or, P(2)=a(2)²-2×2=0

or, P(2)=4a-4=0

or, P(2)=4(a-1)=0

or, P(2)=a-1=0

or, a=1.

thus the value of a is 1.
