Question

x+y+z=m and xy+yz+zx= n find x²+y²+z²​

Answer 1

Step-by-step explanation:

X × X RAISED TO POWER OF 2 = X RAISED TO THE POWER OF 3

X × Y RAISED TO THE POWER OF 2 = XY RAISED TO THE POWER OF 2

X × Z RAISED TO THE POWER OF 2 =XZ RAISED TO THE POWER OF 2

X × - XY = - X2Y

X × - YZ = - XYZ

X × - ZX = - ZX2

DO SAME WITH Y AND Z
