Question

Use the technique of completing the square to transform the quadratic equation into the form (x + c)2 = a. 6x2 + 36x + 18 = 0

Answer 1

first, take out a gcf of 6
x2+6x+3=0
move the constant to the other side:
x2+6x=-3
make a square (6=2 x 3, so it is 3^2)
x2+6x+9=-3+9
(x+3)^2=6
get it?

Answer 2

This is basically college work, and I'm still in High School, we've never talked about this, so I don't understand it.
