What is meant by factoring? A. Removal of redundant variable B. Removal of redundant literal C. Addition of redundant literal D. Addition of redundant variable

The correct answer is A. Removal of redundant variable.

Factoring is the process of finding the prime factors of a number. A prime factor is a factor that is a prime number. A prime number is a number that is only divisible by 1 and itself.

For example, the number 12 can be factored as 2 x 2 x 3. The prime factors of 12 are 2 and 3.

Factoring can be used to simplify expressions. For example, the expression $x^2 + 2x + 1$ can be factored as $(x + 1)(x + 1)$.

Factoring can also be used to solve equations. For example, the equation $x^2 + 2x + 1 = 0$ can be factored as $(x + 1)(x + 1) = 0$. This gives us the solutions $x = -1$ and $x = -1$.

Here is a brief explanation of each option:

• Option A: Removal of redundant variable. This is the correct answer. Factoring is the process of removing redundant variables from an expression.
• Option B: Removal of redundant literal. This is not the correct answer. A literal is a symbol that represents a number. Factoring does not involve removing literals.
• Option C: Addition of redundant literal. This is not the correct answer. Factoring does not involve adding literals.
• Option D: Addition of redundant variable. This is not the correct answer. Factoring does not involve adding variables.
