Find the degree of the polynomial given below: $2$

Find the value of the following polynomial at the indicated value of the variable:
$p(t) = 5t^{2} - 11t + 7$ at $t = a$

If $p(x) = x^2 - 4x + 3$,evaluate: $p(2) - p(-1) + p\left(\frac{1}{2}\right)$

Find $p(0)$,$p(1)$,and $p(-2)$ for the following polynomial:
$p(x) = 10x - 4x^{2} - 3$

State whether the following statement is true or false:
The degree of the polynomial $5x^{2} - 7x + 2$ is $5$.

For the polynomial $\frac{x^{3}+2 x+1}{5}-\frac{7}{2} x^{2}-x^{6},$ write:
$(i)$ the degree of the polynomial
$(ii)$ the coefficient of $x^{3}$
$(iii)$ the coefficient of $x^{6}$
$(iv)$ the constant term
