hartnn (hartnn):

do you know quadratic formula ?

OpenStudy (anonymous):

You have to use ax^2+bx+c=0

hartnn (hartnn):

Compare your quadratic equation with \(at^2+bt+c=0\) find \[a=...?\\b=...?\\c=...?\\\] \[ \\ \sqrt{b^2-4ac}=...?\] then the two roots of t are: \(\huge{t_{1,2}=\frac{-b \pm \sqrt{b^2-4ac}}{2a}}\)

OpenStudy (anonymous):

ok

hartnn (hartnn):

first step is to find a=...? b= ...? c=... ?

OpenStudy (anonymous):

a= 1 b= 4 c=3

hartnn (hartnn):

how did you get those? is your equation, \(t^2+4t+3-0 \) ??
