Question

-4x^2-30x-14

Help! Factor completely

Answer 1

-2(2x^2+15x+7)
it is not factorable b/c 7 cannot be divided by any numbers other than 7 or 1 so use the quadratic formula

Answer 2

So it is prime?

Answer 3

yes

Answer 4

is -2(x+7)(2x+1) a correct answer

Answer 5

No the equation can be factored.

-2(2x^2 + 15x + 7) can be factored further.
It can be factored to -2(2x + 1)(x + 7)

Answer 6

Can you show the steps.

Answer 7

Okay so lets look at 2x^2 + 15x + 7

Break 15x into 14x and x so that we can factor.
2x^2 + 14x + x + 7
2x^2 + x + 14x + 7
x(2x + 1) + 7(2x + 1)

Since there are two same brackets, they combine to form one. The other bracket is formed from x and +7.

Answer: (x + 7)(2x + 1)
Put the -2
-2(x+7)(2x+1)

Answer 8

You just break the middle x value so that you can factor the equation to get two of the same bracket, then afterwards what is left on the outside is the second bracket
