Question

Describe how the x- and y-coordinates of the given quadratic functions C differ from the x- and y-coordinates of corresponding points of y=x^2

x(x+7)^2

Answer 1

$(x+7)(x+7)$

$x(x+7)+7(x+7)$

$x^2+7x+7x+49$

$a=1, b=14, and C=49$

$x=-b/2a$

$x=-14/2$

$x=-7$

$y=x^2$

$y=(-7)(-7)$

$y=49$

$Coordinates(-7,49)$
