What is the factored form of the expression?
t2 – 25
A. (t + 5)(t + 5)
B. (t – 5)(t + 5)
C. (t – 5)(t – 5)
D. (t – 20)(t – 5)
B. (t – 5)(t + 5)
What is the factored form of the expression?
t^2 – 25
A. (t + 5)(t + 5)
B. (t – 5)(t + 5)
C. (t – 5)(t – 5)
D. (t – 20)(t – 5)
B. (t – 5)(t + 5)
To find the factored form of the expression t^2 - 25, we can use the difference of squares formula, which states that a^2 - b^2 can be factored as (a + b)(a - b).
In this case, t^2 is the square of t and 25 is the square of 5. Therefore, we can rewrite t^2 - 25 as (t + 5)(t - 5).
So, the factored form of the expression t^2 - 25 is (t + 5)(t - 5).
The correct answer is B. (t - 5)(t + 5).
