Use the quadratic formula to solve each
of the following quadratic equations.
My answer to this equation was:
x=,x=.
Is this correct? Thanks for your time.
'Fraid it isn't. You've got an extra
"2" factor before the radical. Let's
go through it:
The quadratic formula is:
______
-b ± Öb²-4ac
x = —————————————
2a
where a = 3; b = -2; c = 1
_____________
-(-2) ± Ö(-2)²-4(3)(1)
x = ————————————————————————
2(3)
