Question

HELP ASAP PLEASE

Answer 1

when you have an equation like \(ax^2+bx+c=0\) then
the number
\[ \large \Delta=b^2-4ac \]
tells u what u wany to know

Answer 2

do u know this

Answer 3

yes can you help me solve it

Answer 4

your equation if \(-3x^2+3x+1=0\) then
\[ \large \Delta=3^2-4(-3)\cdot1=9+12=21 \]
then the cuadratic formula tells you that
\[ \large x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}=\frac{-3\pm\sqrt{21}}{-6} \]
is 21 a perfect square?
