Answer 2

Answer:

$\huge\underline\mathfrak\red{sol}\pink{ution}$

$we \: have \\ \\ \implies \red{a {x}^{2} + bx + c} = 0 \\ \\so \: \\ discriminant \: d = \green{ {b}^{2} - 4ac} \\ \\ so \: \\ x = \frac{ - b - \sqrt{d} }{2a} or \red{ \frac{ - b + \sqrt{d} }{2a} } \\ \\ \\ it \: is \: the \: required \: solution$
