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

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!

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).

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
