What does factoring 'in reverse' imply?

• Starting with the answer to find the original problem

• Subtracting instead of adding

• Using division instead of multiplication

• Multiplying instead of dividing

What does the 'greatest common factor' refer to?

• The sum of all factors of a number

• The smallest number dividing a set of numbers

• The product of all prime factors

• The largest number that divides into each term of an expression

How can you verify if your factoring is correct?

• By adding the factors

• By dividing the original expression by the factors

• By multiplying the factors to see if you get the original expression

• By subtracting the factors

What is the first step in factoring an expression like 6x + 3?

• Divide each term by x

• Find the greatest common factor

• Add the coefficients

• Identify the variable

What is the significance of identifying the greatest common factor in an expression?

• It helps in simplifying the expression to its simplest form

• It is used to multiply the terms of the expression

• It determines the highest degree of the polynomial

• It calculates the sum of all terms in the expression

In the expression x^2 + xy, what is the common factor?

• x^2

• y

• xy

• x

Why is it important to check the factored form inside the parentheses?

• To check for possible division errors

• To find any possible errors in addition

• To simplify the expression further

• To ensure no common factors are left

What role does factoring play in solving quadratic equations?

• It is used to find the derivative

• It simplifies the equation for graph plotting

• It is essential for breaking down the equation into solvable parts

• It helps in determining the integral
