The correct option is (B) and (C).

What is equation?

A statement of equality between two expressions consisting of variables and/or numbers. In essence, equations are questions, and the development of a mathematics has been driven by attempts to find answers to those questions in a systematic way.

For example

An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values. For example, 3x + 5 = 15. There are different types of equations like linear, quadratic, cubic, etc.

Given:

x= 5 ± √16

Now, taking the root of 16 which is +4 and -4.

So, x= 5 ± 4

We have two values ,

x= 5+4 or x= 5-4

x=9 or 1

Hence, the solution to x= 5 ± √16 is B. 1 and C. 9.
