Answer 1

$\frac{17}{15} \times \frac{17}{15} + \frac{2}{15} \times \frac{2}{15} - 2 \times \frac{17}{15} \times \frac{2}{15} \\ = { (\frac{17}{15}) }^{2} + {( \frac{2}{15} )}^{2} - 2 \frac{2}{15} \times \frac{17}{15} \\ = ( \frac{17}{15} - \frac{2}{15} ) ^{2} \\ = { (\frac{15}{15} )}^{2} = 1....ans...$
Hope this is ur required answer.
