Question 529624: Please help me with this.I have a project that is 4 parts. I'm not sure how to do this part. I have to do a quadratic formula for x^2 + 6x = 16
I have to
a. put it in standard form
b. state the values of a,b,and c
c. state the quadratic formula
d. show the substitution step
e. show step by step the evaluation of the work until Ireach a solution.
This is very important and I don't want to get it wrong, so I need your help!
thank you so much!

Answer by Alan3354(69443) (Show Source): You can put this solution on YOUR website!
x^2 + 6x = 16
I have to
a. put it in standard form

Or do you mean ?
----------------------
b. state the values of a,b,and c
a = 1
b = 6
c = -16
------------
c. state the quadratic formula

Solved by pluggable solver: SOLVE quadratic equation (work shown, graph etc)

Quadratic equation (in our case ) has the following solutons:

For these solutions to exist, the discriminant should not be a negative number.

First, we need to compute the discriminant : .

Discriminant d=100 is greater than zero. That means that there are two solutions: .

Quadratic expression can be factored:

Again, the answer is: 2, -8. Here's your graph:

----------------
d. show the substitution step
don't know what that means.
------------------
e. show step by step the evaluation of the work until Ireach a solution.
See above.
