Question

______ of the following is the zero of the linear polynomial $p\left(x\right)=9x-27$

• A. $9$
• B. $3$
• C. $-3$
• D. $1/3$

Answer 1

The correct option is B $3$

Zero of polynomial is the value of x for which $p\left(x\right)=0$

$\therefore p\left(x\right)=9x-27$

$\Rightarrow 9x-27=0$

$\Rightarrow x=\frac{27}{9}=3$.
