Question

(l-6)(l-3)=0 are quadratic equations??​

Answer 1

Answer:

yes they are quadratic equations

Answer 2

$\: \: \: \: \: \: \: \: \: \: \: (i - 6)(i - 3) = 0$

$\: \: \: \: \: \: \:i( i - 3) - 6(i - 3) = 0$

$\: \: \: \: \: \: \: {i}^{2} - 3i -6i + 18 = 0$

$\: \: \: \: \: \: \: \: \: \: \: \: \: {i}^{2} - 9i + 18 = 0$
