Answer 1

3?

Answer 2

you need 2 numbers

Answer 3

first of all

\[\huge \color{green}{\text{WELCOME TO OPENSTUDY!}}\]

Answer 4

Thanks Aravind!

Answer 5

\[\Huge{\color{Green}{\rightarrow \boxed{\mathbb{\text{WELCOME}{}}}{\color{green}{\color{blue}TO{\color{purple}O!}}}}} \]

Answer 6

Sorry and Thanks you!

Answer 7

Looks like a perfect square of the form (a+b)^2=a^2+2ab+b^2
if you look at the question as:
(3x)^2+6x+1

Answer 8

Solve the equation using the quadratic formula, equal the whole expression to 0 and proceed, then you'll obtain 2 values of x, for example, if you get x=1 and x=2, to put it as a product you must put it with the sign changed, in this example it would be (x-1)(x-2).
Sometimes you can't use the quadratic formula, I suggest you learn to factor in this order:
1-Common Factor.
2-Notable pars.
3-Ruffini Rule (you should always use this in order to factor powers above 2)
4-Quadratic formula can only be applied when you have an equation in the form Ax^2 + By + c = 0 \[\frac{ -b \pm \sqrt{b^2-4ac} }{ 2a }\]

Answer 9

Thanks
