Question

Factor. 4x2−49y2 Enter your answer in the box.

Answer 1

Answer:

$(2x-7)(2x+7)$

Step-by-step explanation:

Use the identity rule:

$(a^2-b^2) = (a-b)(a+b)$

To factor the given expression:

$4x^2-49y^2$

we can write this as:

$(2x)^2-(7y)^2$

Apply the identity rule we have;

$(2x-7)(2x+7)$

Therefore, the completely factor of the given expression is, $(2x-7)(2x+7)$

Answer 2

4x² - 49y² = (2x)² - (7y)² = (2x - 7)(2x + 7)
