Question

What is the factored form of 8x²-36x-20?

Answer 1

Answer:

(8x+4) ( x-5)

Step-by-step explanation:

Well we can't factor out the 8 and solve because if we do the -20 and -36 will be decimals.

So we do this

8 * -20 = -160

We need to find 2 number that multiplies  to -160 and adds to -36

-40 and 4 fit this category

they add to -36 and multiply to -160

Now we write the equation as

8x^2 - 40x + 4x -20

(8x^2-40x) (4x-20)

8x(x-5) + 4(x-5)

(8x+4) ( x-5)

Answer 2

Answer:

(4x + 2)( 2x - 10)
