Write the degree of each of the following polynomials :
$(i)$ $5 t-\sqrt{7}$
$(ii)$ $3$
$3$, $0$
$1$, $0$
$1$, $1$
$0$, $3$
Verify whether $2$ and $0$ are zeroes of the polynomial $x^{2}-2 x$.
Factorise : $\frac{25}{4} x^{2}-\frac{y^{2}}{9}$
Write $(3a + 4b + 5c)^2$ in expanded form.
Find the value of $k$, if $x -1$ is a factor of $p(x)$ in this case : $p(x)=k x^{2}-\sqrt{2} x+1$
Use suitable identities to find the products : $(3-2 x)(3+2 x)$
