Expand
$(2 x+5 y)^{2}$
Find $p(-2)$ for the polynomial $p(x)=5 x^{2}-11 x+3$
Find $p(0), p(1), p(-2)$ for the following polynomials:
$p(y)=(y+2)(y-2)$
By using the factor theorem, show that $(x+2)$ is a factor of the polynomial $6 x^{3}+19 x^{2}+16 x+4$ and then factorise $6 x^{3}+19 x^{2}+16 x+4$
...... is one of the factors of $p(x)=x^{3}-3 x^{2}+7 x-5$
