someone please help me with this i'm very confused

anonymous · Answer

hint...   use this formula:

$$\LARGE {x_{1/2}} = \frac{{ - b \pm \sqrt {{b^2} - 4ac} }}{{2a}}$$

and you have..a=1  b=-6   c=2

anonymous · Answer

$$\LARGE \Delta  = {b^2} - 4ac$$

$$\LARGE \begin{array}{l}\Delta  > 0\;\;\;\;{\rm{   two solutions}}{\rm{.}}\\Delta {\rm{ = 0\;\;\;\;     one solution}}{\rm{.}}\\Delta {\rm{ < 0    \;\;\;\; no solution}}{\rm{.}}\end{array}$$
