What is the factored form of the expression?
p2 – 49
A. (p + 7)(p + 7)
B. (p – 7)(p + 7)
C. (p – 7)(p – 7)
D. (p – 30)(p – 19)
B. (p - 7)(p + 7)
To find the factored form of the expression p^2 - 49, we need to recognize that it is a difference of squares. The formula for the difference of squares is (a^2 - b^2) = (a + b)(a - b).
In this case, a = p and b = 7. So, we have:
p^2 - 49 = (p + 7)(p - 7)
Therefore, the factored form of the expression is (p + 7)(p - 7).
So, the correct answer is B. (p - 7)(p + 7).
