Question 141308: Which method is best used to find the solutions to:
k(w) = -w^2 + 4
a. Using the square root property
b. Completing the square
c. Using the quadratic formula
d. This cannot be solved since the variable is not 'x'
I selected D; because a,b,c all require a 'x' variable

You can put this solution on YOUR website!
there is nothing special about x __ a variable (unknown) can be designated by any letter

to find the roots of the equation, set the function [k(w)] equal to zero and solve

a. seems to be the best method __ 0=-w^2+4 __ w^2=4 __ w=+- 2
