$\sf \: I \: believe \: this \: is \: the \: answer \: you \: wanted$ ⟹

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

$\boxed{ \sf{Explanation}}$

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

Answer 2

Answer:

see explanation

Step-by-step explanation:

If b² - 4ac = 0

Then the roots are real and equal
