Question

If a+b+c= 10 and ab + bc + ca=25, then find the value of (a+b+c)^2​

Answer 1

We know that

a+b+c=10

Then, (a+b+c)2 =10 ^2 =100

Answer 2

Answer:

100

Step-by-step explanation:

Given:

a+b+c = 10

ab+bc+ca = 25

To find:

(a+b+c)^2

Solution:

If a+b+c = 10

Then,

(a+b+c)^2 = (10)^2 = 100
