Consider the quadratic equation x2 − 6x = 16.
which is equivalent to the given quadratic equation?
a) (x + 4)2 = 16
b) (x − 4)2 = 16
c) (x − 3)2 = 25
d) (x + 3)2 = 16
and
suppose you are completing the square to rewrite 4x2 + 40x = 80 in the form a(x − p)2 = q. what is the first step to take?
a) square half of 40 and add the result to both sides of the equation.
b) subtract 80 from both sides of the equation.
c) factor out 4 from 4x2 + 40x.
d) set the equation equal to zero.
