What is the completely factored form of 8x2 – 50? 2(x + 5)(x – 5) 2(2x – 5)(2x – 5) 2(2x + 5)(2x + 5) 2(2x + 5)(2x – 5)

The factored form of 8x² – 50 is 2 (2x +5)(2x -5) .

Step-by-step explanation:

As given the expression in the question be as follow.

= 8x² - 50

= 2 (4x² - 25)

As

4x² = (2x)²

25 = 5²

Put above values in the expression

= 2 ((2x)² - 5²)

By using the property

(a² - b²) = (a + b)(a - b)

As

a = 2x

b = 5

Thus

= 2 (2x +5)(2x - 5)

Therefore the factored form of 8x² – 50 is 2 (2x +5)(2x -5) .

each side has a different length.
