Hello Forum Members!

The checkbox can be found in the quick reply section below each thread or whenever they post via the advanced post page. We want our members to feel comfortable knowing that their information is being kept private from lurking eyes. Mind you, although your post is made private to the public eye, we still record the necessary information on the poster so that the respective member receives all the appropriate notifications once a reply is made.

Hope this makes your experience here more enjoyable,

Divide by synthetic division: \((2x^3+x^2-22x+20)\div (2x-3)\)



Begin by solving for \(x\) in the divisor:

\(2x-3=0\)

\(\displaystyle x=\frac{3}{2}\)

Now perform synthetic division:



Given a remainder of \(4\), write the expression as:

\(\displaystyle 2x^2+4x-16-\frac{4}{x-\frac{3}{2}}\)

Recall that you set the divisor \(2x-3\) equal to \(0\) at the start. Since \(x\) has a coefficient of \(2\), divide the expression above by \(2\) as well.

\(\displaystyle \frac{\left(2x^2+4x-16-\frac{4}{x-\frac{3}{2}}\right)}{2}\)

Simplify by finding a common denominator in the numerator:

\(\displaystyle =\frac{\frac{\left(2x^2+4x-16\right)\left(x-\frac{3}{2}\right)-4}{x-\frac{3}{2}}}{2}\)

\(\displaystyle =\frac{\left(2x^2+4x-16\right)\left(x-\frac{3}{2}\right)-4}{x-\frac{3}{2}}\div 2\)

\(\displaystyle =\frac{\left(2x^2+4x-16\right)\left(x-\frac{3}{2}\right)-4}{x-\frac{3}{2}}\times \frac{1}{2}\)

Expand and multiply:

\(\displaystyle = \frac{2x^3+x^2-22x+22}{2x-3} \)
If you have endless deck of cards what is the probability of having gotten an ace of spades after being dealt a random card 52 times?

Answer:

An ace of spades occurs once in a 52-card deck.

1/52 chances of getting it.
\(x^4-3x^3+x^2-3x+0=0\)

*Note: Remember to always common factor if a constant doesn't exist - as in this case.

Solution:



Follow this logic when you reach the cubic factor:

For me, I actually liked all flavors, subjects, or categories in mathematics.

Regardless of which one you chose, we can all agree that mathematics can be fun, frustrating, delightful, and discouraging all at the same time.

The compound acrylonitrile can be made in the following reaction:

2C3H6(g) + 2NH3(g) + 3O2(g) → 2C3H3N(g) + 6H2O(g)

A 250.0 L reaction vessel is charged to the following partial pressures at 500°C:

PC3H6 = 10.0 atm
PNH3 = 12.0 atm
PO2 = 9.0 atm

A) What is the total pressure in the vessel just after the reagent gases are added (assume ideal behavior)?  

B) What are the mole ratios of the reagent gases in the vessel before the reaction begins?

C)What is the total pressure in the chamber after the reaction has gone to completion (i.e. all

of at least one of the reactants is used up)?

D) What is the partial pressure of acrylonitrile in the vessel after the reaction has gone to

completion?

E) What mass of acrylonitrile is produced after the reaction has gone to completion?
