Answer» a + B + c = 20 Square on both sides, ( a + b + c )^2 = 20^2 => a^2 + b^2 + c^2 +2( ab + bc + CA ) = 400 putting the given VALUES, => 80 + 2( ab + bc + ca ) == 400 => 2( ab + bc + ca ) = 320 => ab + bc + ca = 320/2 => ab + bc + ca = 160

17.

If a²+b²+c²=80 and a+b+c=20, then fimd the value of ab+bc+ca.

Answer»

a + B + c = 20

Square on both sides,

( a + b + c )^2 = 20^2

=> a^2 + b^2 + c^2 +2( ab + bc + CA ) = 400

putting the given VALUES,

=> 80 + 2( ab + bc + ca ) == 400

=> 2( ab + bc + ca ) = 320

=> ab + bc + ca = 320/2

=> ab + bc + ca = 160
