Find $p(1), p(2)$ and $p(4)$ for each of the following polynomials

$p(y)=y^{2}-5 y+4$

Write the coefficient of $x^{2}$ in the following polynomials

$\pi x^{2}-\frac{22}{7} x+3.14$

Write whether the statement are True or False. Justify your answer.

A polynomial cannot have more than one zero.

By remainder Theorem find the remainder, when $p(x)$ is divided by $g(x),$ where

$p(x)=x^{3}-3 x^{2}+4 x+50, g(x)=x-3$

Factorise

$25 x^{2}+25 x+6$
