When solving this equation by completing the square, which of the following shows the equation with the square completed? x2 - 4x - 32 = 0 Answer (x - 4)2 = 36 (x - 2)2 = 36 (x - 8)2 = 4
@primeralph help me pwease
Get the 32 over on the right side by adding 32 to both sides.
Then divide the coefficient of x by 2, square that number and add it to both sides.
32x^2-36x? is that right?
you can factor x(x-4) = 32
x^2-4x=32
@mebs x(x-4) is already factored.
o alright yea
you both have just lost me?
Why can't you take the equation you were given and add 32 to both sides?
@GreenBeanDemphsey Why can't you take the given equation and add 32 to both sides?
@crombie What are you doing here when you have your own problem to solve?
