if the equation has x2 what can we assume about the line?
its a parabola
solve with the quadratic formula
11x2-9x-21=0
x=1.85
x=-1.032
you'll shake and shudder in surprise...

what is the standard form for lines? (the equation)
y=mx+b
make a table for the equation
y=3x+3
0 1 2 3 4 5

how would you express y and x values in a graph?
(first value) ≤ y ≥ (second value)
(first value) ≤ x ≥ (second value)
solve using quadratic formula:
2x2-8x-3=0
x=4.345
x= -0.345
madness takes its toll...
