Is that Special Products I see?

Step-by-step explanation:

So, we should factor it first. (because that's how we find out).

If you don't know what factoring is, it is basically this:

Thus:

So there's that!

Looking at the problem, we can almost immediately see x as common factor between all three terms.

So:

We have one factor sorted out, but what about the rest?

Let me tell you about a little something called special products:

If you REALLY don't know what I'm talking about, go to Khan Academy.

It goes like this:

But, we are not dealing with that either.

So, to solve this, we need this:

If you just want the answer, here it is:

How did I do this? Simple/ kinda not...(took me a long time to get proficient with this)

Notice the -10 at the end there.

What are the factors?

Then notice the -3 being multiplied with the x.

Somehow, using the factors we just got from -10, we have to get -3 with their sum. (that's how it works)

So, the answer is 2, -5, as their sum is -3. So then we need to put into form:

(x+_)(x+_) (the blanks are where you put the factors)

Thus,

So, Hope this helps! (see answer above)

Adios!

Answer from: serenityarts123

x, x - 5, x + 2

Step-by-step explanation:

Each term in our expression has an x attached to it, so we can check x as one of our factors and pull it out to get the expression

Let's focus on factoring that second term in the product. We'd like to find two numbers that multiply to -10 and add to -3. Let's run through some possibilites:

-1 · 10 = -10, but -1 + 10 = 9; nope!-2 · 5 = -10, but -2 + 5 = 3; closer, but not quite!-5 · 2 = -10, and -5 + 2 = -3; this is our pair!

We'll use this knowledge to split the middle term of and factor:

So our completely factored expression is now , and our factiors are and

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.

Answer from: Quest

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. the cyclic nature of wind and moving sand determines the shape and location of large dunes. at a test site, the prevailing direction of the wind did not change noticeably. however, the velocity did change. fifty-nine wind speed readings gave an average velocity of x = 1075 cm/sec. based on long-term experience, σ can be assumed to be 245 cm/sec. (a) find a 95% confidence interval for the population mean wind speed at this site. (round your answers to the nearest whole number.) lower limit cm/sec upper limit cm/sec
