A is one more A than A, right?

Wrong. a³-a²≠a

It can only be said that a is multiplied by an ace more than a

Wrong, it's not an extra A, it's a time. Because a a = a, a is a times that of a, and a -a is more.

That's right, but note that it's not an extra a, but multiplied by an a, which becomes a power of a, and an extra a a power.

A is more than a to a A

3A is one more ace than 2a

You can test it with the special value method.

The power of 1 is 1, and the power of 1 is also 1, so when a 1, a a when a 1, a 1, a 1

a³－a²＝-2

When a 2, a 8, a 4, a a 4 therefore a can be equal to a and can also be less than or greater than a

It is wrong to have one more a a than a square of a a, and it should be twice the square of more a.

It is true that there is an extra A, but the difference is that there is an extra A

The cube of a is not one more a than the square of a, but the cube of a divided by the square of a is equal to a, a cube is more than a squared, and the cube of a more a minus the square of a, not more a.

It can be said that the former is a times that of the latter, but if a is 1, then it is different, if it is zero.

This particular thing belongs to the category of language......

No, it's an extra ace

Wrong. A cubic is not positive or negative, and a cubic must be positive, so there is not an extra a

1.This phenomenon is likely to be as follows: 2The first is that the pump has not been used for a long time, and the inside of the pump head is rusty, and the water page is stuck, which causes it to not start after powering on, and can only buzz.

3.The second is that the starting capacitance of the water pump is attenuated very badly and cannot achieve the effect of starting. 4.

The first reason is to find a way to get rid of the rust inside and it can rotate normally.

Definitely not! From the meaning of the title:

a³-a²=a²(a-1)

i.e. a more than a (a-1)!

No, the correct answer is as follows:

a^2+a^3=a^2(1+a)

Problem solving: <>

Extension: a 2-a 3 = a 2 (1-a).

Error-prone: the same base.

The powers are multiplied, the base is unchanged, and the exponents are added;

Divide by the power of the same base, the base does not change, and the exponent is subtracted;

The base number is the same, the index is different, and it is not a file and can be directly added or subtracted.

No, the power is not the same, and it cannot be added or subtracted. If only it were changed.

No, it would be nice if the plus sign in the middle was changed to a multiplier sign.

Summary. Of course it's a -a bit bigger.

A -a and -1 which is bigger.

Of course it's a -a bit bigger.

Because a -a = (a - 1 2) -1 4

Its minimum value is -1 4 greater than -1

So no matter what value a takes, a -a is greater than -1.

Hope it helps! Give it a thumbs up!

This is only one question for you, and if you have any extra questions, you can add an order.

a²+a³=a²(1+a)

a²+a³-80=0

a³-64+a²-16=0

a³-4³+a²-a4=0

a-4)(a +4a+16)+(a+4)(a-4)=0a-4)(a infiltration envy +5a+20)=0

So a-4 = 0 or a +5a + 20 = 0

The final result is a=4

The method used to solve the equation is used, and the value of the unknown on the left and right sides of the equation is equal to the solution of the equation. The process of finding the solution of an equation is called solving an equation. The textbook implements the elimination method, that is, using the nature of the imitation of equal sign, the two sides of the equal sign are added, subtracted, multiplied, and divided by the same number of arguments (except 0), and the final goal is to leave only one x on one side

We often use the "Difference Method" to compare the size of these two formulas.

a -2a = a (a-2), when a 0, or.

When a=2, the two terms are equal.

When A 0 or A 2, A is big.

When a is between 0,2, 2a is large.

Another method is the hypothetical method.

It's about setting the former and the latter.

You can solve the second result I mentioned above.

Let the former and the latter solve the first result I mentioned above.

It's not hard to think about it yourself.

a + = a ·a denotes the product of a and a.

a x = (a) denotes the product of a and a.
