: Hello Tutors, I need some serious help here, as This quadriatic form stuff is confusing me to no end. Can someone please help me with this problem?
Write the equation in quadratic form and solve it by factoring.
x^2 + 8(x + 2) = 0
Thank You Tutors for your help. I Greatly Appreciate it! This question is from textbook Intermediate Algebra

Answer by JP(22) (Show Source): You can put this solution on YOUR website!
To set this up in base form for quadratic equations it must look like this...
ax^2+bx+c=0
So, your equation becomes: x^2+8x+16=0
In factored form it becomes: (x+4)(x+4)=0
Both solutions will be the same in this case...but this will usually not be the case.
(x+4)=0
x=-4 or x=-4
I am a little rusty but I think is is called a "double root".
Plug the solution -4 in for every instance of x to prove the solution is valid.
4^2+8(-4)+16=0
16+-32+16=0
-16+16=0
0=0
