Answer:

49x²-16 = (7x - 4)(7x + 4)

Step-by-step explanation:

Your "49×2-16" is incorrect; did you mean "49x^2-16" or "49x²-16?"

This last expression is the difference of two squares.

The formula for that is a² - b² = (a - b)(a + b), and so your 49x²-16 factors as follows:

49x²-16 = (7x - 4)(7x + 4)
