Question

Factor completely. 2x^4 + 4x^3 - 30x^2 =

Answer 1

Answer:

2x^2(x + 5)(x - 3).

Step-by-step explanation:

The Greatest Common Factor is 2x^2, so:

2x^4 + 4x^3 - 30x^2

= 2x^2(x^2 + 2x - 15)    Now we factor the quadratic in the parentheses:

= 2x^2(x + 5)(x - 3).

Answer 2

Answer:

$2x^2(x-3)(x+5)$

Step-by-step explanation:

The first thing that you can do is to factor out an x^2 from the expression.

x^2(2x^2+4x-30)

The next step is to factor out a 2.

2x^2(x^2+2x-15)

Finally, you can factor the quadratic inside.

2x^2(x-3)(x+5)

And now you're finished! Hope this helps!
