Question

find the zero of the polynomial p(x)=-9x+9

Answer 1

Answer:

-1

Step-by-step explanation:

Putting -1 in place of x

that means p(-1)=9*(-1) +9

= -9 + 9=0

HENCE -1 IS THE ZERO OF POLYNOMIAL

HOPE ITS HELP

Answer 2

Answer :

The zero of the polynomial of p(x) = 9 - 9x is (1)

Explanation :

Given,

• A real number a is the zero of the polynomial if p(x) if p(a) = 0

so here,

• p(x) = ( 9 - 9x )

$\implies \: 0 = 9 - 9x$

$\implies \: - 9 = - 9x \\ \\ \implies \: x = \frac{ - 9}{ - 9}$

$\implies \: x = \cancel \frac{ - 9}{ - 9}$

$\implies \: x \: = 1$

Therefore, the value of x is (1).

Verification :

p(1) = ( 9 - 9(1))

p(1) = 9-9

p(1) = 0

since, p(1) = 0,

it is concluded that , the zero of the polynomial of p(x) is 1.
