MAT 126 Week 3 Assignment Projects on working equation problems
When we are working with equation problem it is very important that we refresh yourself on them because they can be tricky. When doing an equation problem and you haven’t done them in a long time it can cause must confusion. With these two projects it was kind of challenging to me because it has been a while since we have done these. But as you can see from the working that I have done before it comes back to you eventually. The problems below show all the steps to doing these two projects
Project 1 Problem C: x2+12x-64=0
a) Move constant term to the right side of the equation.
x2+12x-64+64= 0+64
x2+ 12x = 64
b) Multiply each term in the equation by four times the coefficient of the x2 term:
x2+ 12x= 64
(4)x2+(4)12x = 64(4)
4x2+48x = 256
c) Square the coefficient of the original x term and add it to both sides of the equation. The original x term is 12 so you have to 12 squared which = 144. So I then added 144 to both sides.
4x2+ 48x +144 = 256 + 144= 400
