What is the expression in factored form? 25x^2 - 49

25x^2 - 49 = (5x-7)(5x+7)

Step-by-step explanation:

Given the expression is 25x^2 - 49.

We can compare the given problem with "Difference of square formula" i.e. a^2 - b^2 = (a-b)(a+b).

We have 25x^2 - 49.

25x^2 - 49 = (5x)^2 - (7)^2

25x^2 - 49 = (5x-7)(5x+7)

Hence, the factored form is 25x^2 - 49 = (5x-7)(5x+7).

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
