Answer to ths equatii; - 3x=81.

show the work.

-3x = 81.

Let's divide left and right by - 3 to isolate x.

-3x/-3 = 81/-3

Simplify:

x = - 27

I found: 9 x2 + 54x + 81

steps:

Your square can be "translated" as:

(3x+9) 2 = (3x+9) (3x+9) =

multiplying we get:

= (3x⋅3x) + (3x⋅9) + (9⋅3x) + (9⋅9) =

=9 x2 + 27x+27x+81=

and finally:

=9 x2 + 54x + 81
