`\sf If \: the \: discriminant \: of \: an \: equation \: is \: zero, \: then \\ \sf \: the \: equation \: will \: have \:\underline{ 1 \: real \: solution \: with \: real \: and \: equal \: roots}.`

`\boxed{ \sf{Explanation}}`

`\sf If \: discriminant \: of \: quadratic \: equation \: ax^(2) + bx + c \: \\ \sf is \: b^(2) - 4ac = 0 \: then \: it \: will \: have \\ \sf↦\underline{1 \: real \: solution \: with \: real \: and \: equal \: roots.}`
