Q. x2−36Which of the following is equivalent to the given expression?Choose 1 answer:(A) (x−6)2(B) (x+6)2(C) (x−6)(x+6)(D) x(x−36)
Recognize the expression: Recognize the given expression as a difference of squares.The expression x2−36 can be factored because it is a difference of two perfect squares. The general form of a difference of squares is a2−b2=(a−b)(a+b).
Identify a and b: Identify a and b for the difference of squares.In the expression x2−36, a is x and b is 6 because x2 is the square of x and 36 is the square of 6. Therefore, a2=x2 and b2=36.
Apply the difference of squares formula: Apply the difference of squares formula.Using the formula from Step 1, we can rewrite x2−36 as (x−6)(x+6).
