Write in vertex form (by completing the square)y=4x2+40x+96

Answers

$y=4x^2+40x+96\n \n The \ vertex \ form \ of \ the \ function \ is: \n \ny = a(x - h)^2 + k \n \nvertex =(h, k) \ is \ given \ by: \n \nh = (-b)/(2a) , \ \ \ k = c -(b^2)/(4a) \n \na=4 , \ \ b=40 , \ \ c=96$

$h = (-40)/(2 \cdot 4)=(-40)/(8)=-5 \n \n k = 96 -(40^2)/(4 \cdot 4) =96-(1600)/(16) =96-100=-4 \n \n y = 4(x - (-5) )^2 + (-5)=4(x +5 )^2 -5$
