Can X divide by X?

Can X divide by X?

Nothing! The practice problems above have x terms instead of 0, so it might seem all right at first to divide by x and reduce these problems. However, we don’t know what number x represents, so we can’t divide by x in case it stands for 0.

When a number is divided by 1 the answer is?

itself
Any number divided by 1 equals itself. This rule tells us simply that if we have a number divided by 1, our answer will equal that number regardless of what that number is. We don’t even have to pay that much attention to the number we are dividing.

What is a divided by 1?

Any number divided by 1 equals itself. This rule tells us simply that if we have a number divided by 1, our answer will equal that number regardless of what that number is. We just have to make sure that when dividing any number by 1, we remember the answer is always itself.

What does divided by look like?

÷
The division sign (÷) is a symbol consisting of a short horizontal line with a dot above and another dot below, used to indicate mathematical division.

How do you divide two polynomials?

Dividing Polynomials Using Long Division

1. Divide the first term of the dividend (4×2) by the first term of the divisor (x), and put that as the first term in the quotient (4x).
2. Multiply the divisor by that answer, place the product (4×2 – 12x) below the dividend.
3. Subtract to create a new polynomial (7x – 21).

How do you synthetically divide?

Synthetic division is another way to divide a polynomial by the binomial x – c , where c is a constant.

1. Step 1: Set up the synthetic division.
2. Step 2: Bring down the leading coefficient to the bottom row.
3. Step 3: Multiply c by the value just written on the bottom row.
4. Step 4: Add the column created in step 3.

How to divide x2 x 2 into a dividend?

Divide the highest order term in the dividend x2 x 2 by the highest order term in divisor x x. Multiply the new quotient term by the divisor. After changing the signs, add the last dividend from the multiplied polynomial to find the new dividend. Pull the next terms from the original dividend down into the current dividend.

How to divide a polynomial by a divisor?

Set up the polynomials to be divided. If there is not a term for every exponent, insert one with a value of 0 0. Divide the highest order term in the dividend x2 x 2 by the highest order term in divisor x x. Multiply the new quotient term by the divisor.

How to divide x3 x 3 by the highest order term?

If there is not a term for every exponent, insert one with a value of 0 0. Divide the highest order term in the dividend x3 x 3 by the highest order term in divisor x x. Multiply the new quotient term by the divisor. After changing the signs, add the last dividend from the multiplied polynomial to find the new dividend.

What is the remainder of a polynomial divided by?

If a polynomial is divided by $(x-1)$ then remainder is 5 and if divided by $(x-2)$ the remainder is 7.
