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

Anestetic [448]

$y=4x^2+40x+96\\ \\ The \ vertex \ form \ of \ the \ function \ is: \\ \\y = a(x - h)^2 + k \\ \\vertex =(h, k) \ is \ given \ by: \\ \\h = \frac{-b}{2a} , \ \ \ k = c -\frac{b^2}{4a} \\ \\a=4 , \ \ b=40 , \ \ c=96$

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

describe the error Kevin made. circle the places in the drawing of Kevin's solution where he made an error

Tresset [83]

The error that Kevin made was he did not include two units (see the circled areas) while counting the units. He counted the units there as one instead of two at those junctions. The correct measure of the perimeter of the figure is 20 units.
