Question

If you factor 4x^2-49y^2 what’s the answer

Answer 1

The given Equation is 4x² - 49y²

Spilt it in the form of a² - b² :

☞4x² - 49y²

☞ (2x)² - (7y)²

☞ ( 2x + 7)(2x -7 )

Answer:

More information: { Identity Used }

☞ a² - b² = (a + b)(a-b)

☞ (a + b)² = a² + b² + 2ab

Answer 2

(2x - 7y)(2x + 7y)

Explanation:

4x^2-49y^2 is the difference of two squares: (2x)² - (7y)².

This is a case of "special products and factoring."

Since a² - b² = (a - b)(a + b),

(2x)² - (7y)² = (2x - 7y)(2x + 7y)
