Answer:

hey here is your answer

B) 0,3

Step-by-step explanation:

To find zero of this P(x) Equation

{x}^{2} - 3x = p(x)x

2

−3x=p(x)

Take P(x)=0

\begin{lgathered}{x}^{2} - 3x = 0 \\ \\ \therefore \: x(x - 3) = 0 \\ \\ \therefore \: x = 0 \: \: \: \: or \: \: \: \: (x - 3) = 0\end{lgathered}

x

2

−3x=0

∴x(x−3)=0

∴x=0or(x−3)=0

First zero x= 0

\begin{lgathered}x - 3 = 0 \\ \\ \therefore \: x = 3\end{lgathered}

x−3=0

∴x=3

second zero x= 3

zeroes of P(x) = x²-3x Are 0 & 3
