Question

prove that two and 0 are zeros of p(x)=x2-2x​

Answer 1

Answer:

It can be proved as follows:

• $\fbox {For\:x=0}$

${x}^{2} - 2x \\ (0) {}^{2} - 2(0) \\ 0 - 0 \\ 0$

So 0 is zero of given polynomial.

• $\fbox {For\:x=2}$

${x}^{2} - 2x \\ (2) {}^{2} - 2(2) \\ 4 - 4 \\ 0$

So it is also zero of polynomial
