Question

Find the type and number of solutions for the equation:

2x2 + 18 + 12x = 0

Answer 1

\[2x^2+18+12x=0\] It is Quadratic Polynomial.

Answer 2

2x^2 + 18 + 12x = 0
2(x^2+9+6x)=0
x^2+9+6x=0
(x+3)^2=0
x+3=0
x=-3

Answer 3

& it has two solutions :)

Answer 4

\[x ^{2}+6x+9=0\]

Answer 5

got it @tonio5ilva ?

Answer 6
