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
