Answer 1

Answer:

Given (a+b+c)²=a²+b²+c²+2ab+2bc+2ca

a=2 ,b= -1,c=3

Step-by-step explanation:

Left hand side :

(a+b+c)²

→{2+(-1)+3}²(4)²=16........(1)

Right hand side

a²+b²+c²+2ab+2bc+2ca

→2²+(-1)²+3²+{2.2.(-1)}+{2.(-1).3}+{2.3.2}

→4+1+9+(-4)+(-6)+(12)

→14-4-6+12

→14-(4+6)+12

→14-10+12

→4+12

→16.........(2)

Left hand side=Right hand side(proved)
