Factoring trinomials,help?

borishaifa [10]

Hey there!

When factoring trinomials, we're usually looking at the trinomial in the format of:

ax^2 + bx + c

In order to factor these, we have to use a different method than when a<1. When a is less than one, we can simply figure out the factors that add to the middle term and multiply to the last, but here we have to do a little something different.

The first step is to factor out the GCD of these terms. As you can see, there isn't one, as 13 is prime.

The next step is to multiply a by c:

6(6) = 36

Next, we have to, using the pattern of trinomials(the two binomials would have factors that add to the middle term and multiply to the last), we have to find factors of 36 that multiply to 36 and add to -13. When we do this step, we can disregard the last term for now. Let's list factors of 36:

36 =
18, 2 = 20
9,4 = 13
-9, -4 = 13

-9 and -4 work for this. We can now write them as x terms and factor by grouping:

6m^2 - 4m - 9m + 6 (don't forget that last term)

For the left side, factor out a 2m:

2m(3m - 2)

For the right side, factor out a -3:

2m(m-2) - 3(m-2)

Now that we have our common factor of m-2, we can write them as a product of 2 binomials:

(2m-3)(m-2)

Hope this helps!

Imagine you are trying to maximize the calories you burn in a 60-minute workout you do a few times a week. Running burns 9 calor

amm1812

Running burns the most calories folwed by aerobic

so max out the most and min the least

most running
running has no limit, so see least

aerobic, aerobic has to be at most 30 (less than 30)

rowing has to be at least 15 mins
say row=15 mins

then you have 45 mins left
max out on running (minus 1 tho to do running)

so
44mins running 1 min run, 15min row
total calories=507 calories burned

the way to do it is
x=running minutes
y=aerobic minutes
z=rowing minutes

x+y+z=60
9x+6y+7z=max calories
x≥5
y≤30
z≥15
those are the equations
not sure what the objective function is

Ben works for software company in Cleveland. To train new employees, Ben travels to their two other locations, Buffalo and Phila

Andru [333]

Answer:

Explanation:we will solve this question with help of linear programming.

Now, let Ben goes x times in buffalo trip and goes y times in Philadelphia trip. Thus, according to the question, Min Z= 180x+300y

And s.t.r. 2x+3y≤105, where x≥5, y≥15.

since at (0,0) 0≤105(true), so area of 2x+3y≤105 will cover the origin.

But, 0≥5 and 0≥15 are false, so their area will not cover the origin.

Thus, after drawing the graph of these three lines we will get a feasible reason of triangle ABC, where point A≡(5,31.667), B≡(5,15), and C≡(30,15)

Z at A- 180×5+300×31.667=10,400.1

at B-180×5+300×15=1350( which is minimum.)

at C- 180×30+300×15=5,850

Thus, Ben should go 5 times to buffalo trip and 15 times to Philadelphia to minimize his cost which is $1350.
