निम्नलिखित प्रत्येक व्यंजक के गुणनखण्ड़ कीजिए:
`x(x+z)-y(y+z)`

Simplify: x(x-y)+y(y-z)+z(z-x)

If x + y = 2z then (x)/(x-z) +(z)/(y-z) = ?

What is the proportion equivalent to x/y :y/z:x/z , if X : Y :Z = 4 : 7 : 9? x/y :y/z:x/z के समतुल्य समानुपात ज्ञात करें , यदि X : Y : Z = 4 : 7 : 9 है |

A person travels three equal distances at a speed of x km/hr, y km/hr and z knyhr respectively. What is the average speed for the whole journey? (x y z)/(3(x y+y z+z x)) b. (x y z)/((x y+y z+z x)) c. ((x y+y z+z x))/(x y z) d. (3x y z)/((x y+y z+z x))

Determinant (x-y)(y-z)(z-x)(x+y+z)
