You asked:

Evaluate the expression: \(\left(1.2 x - 0.8 y\right) \cdot \left(1.2 x + 0.8 y\right)\)

MathBot Answer:

Evaluated



\(\displaystyle \left(1.2 x - 0.8 y\right) \cdot \left(1.2 x + 0.8 y\right) = \left(\frac{6 x}{5} - \frac{4 y}{5}\right) \left(\frac{6 x}{5} + \frac{4 y}{5}\right) \)

Expanded

\[\left(1.2 x - 0.8 y\right) \cdot \left(1.2 x + 0.8 y\right) = \frac{36 x^{2}}{25} - \frac{16 y^{2}}{25}\]

Factored

\[\left(1.2 x - 0.8 y\right) \cdot \left(1.2 x + 0.8 y\right) = \frac{4 \cdot \left(3 x - 2 y\right) \left(3 x + 2 y\right)}{25}\]
