Answer 1

$5. If\: p(x) = ax^{2} + bx + c\: is \:a \:quadratic$

$polynomial\: then\: what\: is\: relation \:of \:$

$\frac{c}{a}\: with$

$\underline {\pink{ product \:of \: zeroes .}}$

$Option \: \green { (d) } \:is \: correct.$

$7.\: When\: the\: graph \:of \:pair \:of\: linear$

$equations \:intersect \:at\: a \:point,\: then$

$the\: system \:of \:equation\: have$

$\underline{\pink{Unique \: solution . }}$

$Option \: \green { (a) } \:is \: correct.$

$8. Probability\: of\: an\: event\: E$

$+ probability\: of \:the \:event\: 'not \: E =$

$\underline {\pink{ 1}}$
