Question

$\frac{0.25 {x}^{2} - 0.8xy + 0.6 {y}^{2} - 0.09 {z}^{2}}{0.5x - 0.8y - 0.3z}$
Please answer this!!​

Answer 1

$\frac{0.25 {x}^{2} - 0.8xy + 0.6 {y}^{2} - 0.09 {z}^{2}}{0.5x - 0.8y - 0.3z}$

$= \frac{ \frac{1}{4}x {}^{2} - \frac{4}{5}xy + \frac{3}{5}y {}^{2} - \frac{9}{100} z {}^{2} }{ \frac{1}{2} x - \frac{4}{5}y - \frac{3}{10}z }$

$= \frac{25x {}^{2} - 80xy + 60y {}^{2} - 9z {}^{2} }{50x - 80y - 30z} //.$

Answer 2

$100 + 100 = 200 + 200 = 400$
