@pooja195 these are he answer choices!
>_< GRRR!!! they want the quadratic formula TTT_TT
ok B) what are the a b c values? :)
x^2 8 and 4
fair enough a=1 b=8 c=4 \[\huge~x=\frac{ -b \pm \sqrt{b^2-4ac} }{ 2a } \]
\[\huge~x=\frac{ -(8)\pm \sqrt{(8)^2-4(1)(4)} }{ 2(4) }\]
okay!
eh it looks overwhelming :/ (8)^2−4(1)(4)=?
48?
\[\huge~x=\frac{ -8 \pm \sqrt{48} }{ 2}\]
@jagr2713 how do i finsih this?
@danial.sheikh
wait
HINT: \(48 = 16\cdot3\)
\(\huge~x=\frac{ -(-8) \pm \sqrt{48} }{ 2}\)
which simplifies to: \(\huge~x=4 \pm 2\sqrt{3} \) using \(\large \sqrt{a^2b}=a\sqrt b\)
@pooja195 so what is the next step?
Look at what @mathmate showed u .-.
okay!
so A?
go_od job :) it is A
