Answer 2

x2 + 5x + 2 = 0
Please show the detail method. HELP!
Thanks. :)

Answer 3

completing the square involves an identification of the coefficients
in the general form
Ax^2 + Bx + C = 0

you would need to
divide the coefficient B by two
then square it
add it to the entire equation then you should be able to factor easily

Answer 4

Ax^2 + Bx = C General form
(B/2)^2

Ax^2 + Bx + (B/2)^2 = C + (B/2)^2
then put it back to general form
