Question

the equation a(x-b)(x-c)/(a-b)(a-c) +b(x-c)(x-a)/(b-c)(b-a)+c(x-a)(x-b)/(c-a)(c-b)=x is satisfied by how many values of x? (Please explain)​

Answer 1

Answer:

the equation

a(x-b)(x-c)/(a-b)(

a-c) +b(x-c)(x-a)/(b-c)(

b-a)+c(x-a)(x-b)

/(c-a)(c-b)=x is

satisfied by how many values of x

Answer 2

Answer:

All values of x.

Step-by-step explanation:

f(a)=0

f(b)=0

f(c)=0.

x satisfies more than two values. (The degree of x here is 2)

So it's an identity.
