Answer 1

Answer:

The answer is the (a²+b²+c²)= 29

Step-by-step explanation:

The formula is the (a+b+c)²= a²+ b²+c² +2(ab+bc+ca)

Given : a+b+c = ab+bc+ca =26

Now putting the value above the formula

we get

(9)²=a²+b²+c²+2×26

81= ( a²+b²+c²) +52

(a²+b²+c²) = 81-52

a

(a²+b²c²)= 29 ( Answer)
