Y = 3x^2 + 6x -2 y = 3(x^2 + 2x ) - 2 complete the square on the x^2 + 2x. y = 3(x^2 + 2x + 1) -2-3 y = 3(x+1)^2 -5 vertex is (-1, -5); AOS is x = -1; opens upward
y = x^2 + 9x + (81/4) this will factor y = (x + 9/2)^2 vertex is (-9/2, 0); AOS is x = -9/2; opens upward
2% take the absolute value of your (experimental-accepted then divide by the accepted) so (20-25)/25=.2 then multiply that number by 100 to get the percent, .2*100=2
