Factor 2x2 − 4x − 30 completely. (5 points) 2(x − 5)(x + 3) 2(x − 3)(x + 5) (2x + 3)(x − 5) (2x − 5)(x + 3)
balandron [24]

Answer:

The answer is

<h2>2( x + 3)(x - 5)</h2>

Step-by-step explanation:

To factor the expression

2x² - 4x - 30

<u>First factor 2 out of the expression</u>

That's

2( x² - 2x - 15)

<u>Next write - 2x as a difference</u>

2( x² + 3x - 5x - 15)

<u>Factor out x from the expression</u>

That's

2 [ x( x + 3) - 5x - 15 ]

<u>Factor out </u><u>-</u><u>5 from the expression</u>

2 [ x ( x + 3) - 5( x + 3) ]

<u>Factor out x+3 from the expression</u>

We have the final answer as

<h3>2( x + 3)(x - 5)</h3>

Hope this helps you
