Question

The linear polynomial p(x)=7x–3 has the zero ........,Select a proper option (a), (b), (c) or (d) from given options so that the statement becomes correct.
(a) 7/3
(b) 3/7
(c) -7/3
(d) -3/7

Answer 1

Hi ,

p( x ) = 7x - 3

To find zero of polynomial we have to

take p( x ) = 0

p( x ) = 0

7x - 3 = 0

7x = 3

x = 3/7

option ( b ) is correct.

I hope this helps you.

Answer 2

P(x) = 7x -3

= 7 (x-3/7)

Now
P(3/7) = 7( 3/7 - 3/7)

=7 (0)

= 0

Hence 3/7 is a zero of P(x)

I hope this answer helps you
