Your buddy says
x^2+10x = -20
can be solved by completing the square or factoring.
Is your buddy wise?
What is NO, factoring won't work because solutions are not rational numbers
An object dropped on Jupiter, with
g=76(ft)/(sec^2)
is modeled by
h=g/2t^2+hi
hi = initial height, t = time, h = height
The most effective method to calculate when the object hits the ground is
A) factor B) graph c) complete the square
D) square root method
What is D, because when the object hits the ground, h = 0, thus taking square root is quick and easy.
