Answer 1

Answer:

No corrections....Your answer is completely right!

Verification:

$= > 3 \times{ ( \frac{ - 1}{2} )}^{2} + 2 \times (\frac{ - 9}{4} ) \times ( \frac{ - 1}{2} ) - 3 \\ = > 3 \times ( \frac{1}{4} ) + ( \frac{9}{4}) - 3 \\ = > ( \frac{3}{4} + \frac{9}{4} ) - 3 \\ = > \frac{12}{4} - 3 \\ = > 3 - 3 \\ = > 0 \\ hence \: \: \: \: \: \: proved.$

Hope this answer helps you ^_^ !
