You know what I think that other guy is really foul so I will answer your question for da brainliest

Step 1: (( 18 * (x^3)) + 5x^2) - 2x

Step 2: what you need to do is figure out what this equation really means but here I will tell you

The real step 1 is multiply the coefficient of the first term by the constant 18 times negative 2= negative 36

Step 2: find two factors of negative 36 whose sum is equals the coefficient of the middle term, which is 5.

-36 + 1 = -35

-18 + 2 = -16

-12 + 3 = -9

-9 + 4 = -5

-6 + 6 = 0

-4 + 9 = 5 that’s it

So your answer will be x times (9x - 2) times ( 2x + 1)
That is your answer
Hope this helped

ben drives from a 36- foot platform. The equation h= -16t^2+14t+36 models the dive. How long will it take Ben to reach the water
Valentin [98]
So you want to plug in the height for h and solve for t

36 = -16t^2+14t+36
So you get 14/16 which simplifies to
7/8 seconds
