What is the factored form of the expression? r2 – 49
(r – 7)(r + 7) * my answer
(r + 7)(r + 7)
(r – 7)(r – 7)
(r – 7)(r + 9)
I agree with Ashley that your answer is correct.
In order to get r^2 - 49, you have have the equation in A. Then, you would multiply the like terms together to get the final answer of r^2 - 49.
(r - 7)(r +7) = r^2 - 49
r x r = r^2
-7 x 7 = -49
r^2 - 49 = r^2 - 49
So yes, A is the correct answer.
You are correct!
The correct factored form of the expression r^2 - 49 is (r - 7)(r + 7). So, your answer is correct. Well done!
To find the factored form of the expression r^2 - 49, we need to factorize the expression by applying the difference of squares formula. The difference of squares formula states that a^2 - b^2 can be factored as (a - b)(a + b).
In our case, a = r and b = 7. Therefore, we can write r^2 - 49 as (r - 7)(r + 7).
So, your answer (r - 7)(r + 7) is correct.
