Question

Factor Completely.
(0.01y^2-0.0009)

Answer 1

how annoying. difference of two squares

Answer 2

\[a^2-b^2=(a+b)(a-b)\] and here
\[a=0.1x,b=0.03\]

Answer 3

Sateliteeeeeeeeeeeeeeee!

Answer 4

\[\large 0.01y^2-0.0009\]



\[\large \frac{1}{100}y^2-\frac{9}{10000}\]



\[\large (\frac{y}{10})^2-(\frac{3}{100})^2\]



\[\large (\frac{y}{10}-\frac{3}{100})(\frac{y}{10}+\frac{3}{100})\]

Answer 5

Alternatively,


\[\large 0.01y^2-0.0009\]


\[\large (0.1y)^2-(0.03)^2\]


\[\large (0.1y-0.03)(0.1y+0.03)\]
