Question

hey guys solve it pls

Answer 1

answer will be
$0.5x - 0.8y + 0.3z$

Answer 2

${Answer :-}$

We know that,
( a - b) ^2 = a^2 - 2ab + b^2

Now, we have,.
[0.25x^2 - 0.8 xy + 0.64y^2 - 0.09z^2] / (0.5x - 0.8y - 0.3z)

= [ {(0.5x) ^2 - 2*0.5x*0.8y + (0.8y)^2} - (0.3z)^2 / (0.5x - 0.8y - 0.3z)

= [ {0.5x - 0.8y} ^2 - (0.3z)^2] / (0.5x - 0.8y - 0.3z)

Again, we have a^ - b^2 = (a+b) (a-b)

= (0.5x - 0.8y + 0.3z)(0.5x - 0.8y - 0.3z) / ( 0.5x - 0.8y - 0.3z)

= (0.5x - 0.8y + 0.3z)

Hope this helps,.
