you facordo es 1 x 3-y®+1252°+

Say2


plz do answer guys I will mark u as brainliest ​

Answer 1

Step-by-step explanation:

(x/3)^3 + (-y)^3 +(5z)^3

-3×(x/3)×(-y)×5z

(x/3 -y +z)(x^2/9+y^2 +25z^2 +xy/3+5zy-5xz/3)

Answer 2

${( \frac{x}{3}) }^{3} + { (- y)}^{3} + {(5z)}^{3} - 3( \frac{x}{3} )( - {y})(5z) \\ ( \frac{x}{3} - y + 5z)( \frac{ {x}^{2} }{9} + {y}^{2} + 25 {z}^{2} + \frac{xy}{3} + 5yz - \frac{5xz}{3} )$
by using formula

x³ + y³+ z³- 3xyz = (x+y+z)(x²+ y²+ z²- xy- yz - xz)
