If x+y+z=9, xy+yz+zx =26; find x²+y²+z²
vichka [17]
<em>First, we must expand  and simplify :</em>
x + y+z = 9

(x + y+z)^{2} = (9)^{2}

x^{2} + y^{2}+z^{2} + 2(xy + yz+zx) = 81

<em>And Than, Enter the value :</em>

x^{2} + y^{2}+z^{2} + 2(26) = 81

x^{2} + y^{2}+z^{2} + 52 = 81

x^{2} + y^{2}+z^{2} = 81- 52

\boxed{x^{2} + y^{2}+z^{2} = 29}
