Answer 1

Answer:

yes it is an quadratic equation because the degree is 2 and when there is degree of 2 for any polynomial then that equation is called as quadratic

Answer 2

Answer:

$13 = - 5y ^{2} - y$

$5 {y}^{2} + y + 13 = 0$

y is only the variable in given equation & highest index of variable is 2.

hence the given equation is quadratic equation..
