Question 151087
sqrt7 & sqrt23=7^(1/2), 23^(1/2)
2x^6-10x^5+14x^4
----------------------
2x^4(x^2-5x+7)
---------------------
24-11r+r^2
(8-r)(3-r)
---------------------
y=x^2+2x-3
{{{ graph( 300, 200, -6, 5, -10, 10, x^2 +2x -3 ) }}} (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, x^2 +2x -3 ). 
x intercepts=(1,0) & (-3,0)
