Question

Find the following product:
4.1xy(1.1x − y)

Answer 1

To find the product, we will use distributive law as follows:

\[4 . 1xy\left( 1 . 1x - y \right)\]

\[ = \left( 4 . 1xy \times 1 . 1x \right) - \left( 4 . 1xy \times y \right)\]

\[ = \left\{ \left( 4 . 1 \times 1 . 1 \right) \times xy \times x \right\} - \left( 4 . 1xy \times y \right)\]

\[ = \left( 4 . 51 x^{1 + 1} y \right) - \left( 4 . 1x y^{1 + 1} \right)\]

\[ = 4 . 51 x^2 y - 4 . 1x y^2\]

Thus, the answer is \[4 . 51 x^2 y - 4 . 1x y^2\].
