$\bf \begin{array}{llccll}
y=&1x^2&-6x&+9\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}\qquad discriminant\implies b^2-4ac$

so... what does that give you for the discriminant?

if it's a negative value, no solutions
if it's a positive value, two solutions
if it's 0, one solution

Find the distance between the points given.<br><br> (2, 2) and (5, 5)

mario62 [17]

Distance between two points, d, is given by
$d= \sqrt{ ( x_{2} - x_{1}) ^{2} + (y_{2} - y_{1}) ^{2} }
$
where: (x1, y1) = (2, 2) and (x2, y2) = (5, 5)
$d= 
\sqrt{ ( 5 - 2) ^{2} + (5 - 2) ^{2} } \\ d= \sqrt{ (3)^{2} + 3^{2} } 
\\ d= \sqrt{9+9} \\ d= \sqrt{18} \\ d=3\sqrt{2} \ units$
