Answer 2

$\large{ \bold{ \red{ \underline{ \underline{Question...}}}}}$

$\large{ \sf{the \: discriminant \: of \: the \: quadratic}} \\ \large{ \sf{equation \: {x}^{2} + 5x + 5....}}$

$\large{ \green{ \bold{ \underline{ \underline{Answer...}}}}}$

$\large{ \sf{ \to \: D = 5}}$

$\large{ \bold{ \red{ \underline{ \underline{Solution...}}}}}$

$\large{ \sf{ \to \: u \: must \: know..}} \\ \\ \large{ \sf{for \: a \: polynomal \: p(x) = a {x}^{2} + bx + c}} for \: \\ \\ \boxed{ \green{ \large{ \sf{D = {b}^{2} - 4ac}}}}$

$\large{\sf{ \to \: given \: f(x) = {x}^{2} + 5x + 5}} \\ \\ \large{ \sf{ \to \: by \: comparing \: f(x) \: with \: a {x}^{2} + bx + c}} \\ \\ \large{ \sf{ = > D = (5) {}^{2} - 4 \times (1) \times (5)}} \\ \\ \large{ \sf{ = > D = 25 - 20}} \\ \\ \large{ \sf{ \red{ \boxed{ = > D = 5}}}}$
