You subtract a polynomial by adding its additive inverse. For example, subtracting (x - y) is the same as adding (-x + y). Alternately, you can simply subtract similar terms - that is, subtract the coefficients (the numbers) for terms that have the same combination of variables.

Adding and subtracting polynomials is simply the adding and subtracting of their like terms.

A fourth degree polynomial.

is -4 a polynomial? This depends on what you accept as a definition A polynomial is often defined as a set of things in order obeying certain rules. ( these things and rules can be very complicated) A polynomial EQUATION is an equation between two polynomials When using only real numbers and "regular" math rules -4 is a polymomial of degree 0 x = -4 is a polynomial equation is a polynomial of degree 1 it is the same as x +4 = 0 It can be represented by { 4, 0} Sometimes the terms are used interchangably

Why is it important to simplify radical expressions before adding or subtracting? How is adding radical expressions similar to adding polynomial expressions? How is it different? Provide a radical expression for your classmates to simplify..

Subtracting a negative is the same as adding the equivalent positive. For example, subtracting minus 10 is the same as adding 10.

Ensure that the denominators are the same when adding or subtracting fractions.

That's a polynomial expression.

They aren't. The rules are the same as those for adding/subtracting or multiplying integers. Just be careful of the decimal point's location.

line up the decimal point when your adding and subtracting. add annex a zero when you have extra number. sometimes you can use a number line.

If their denominators are different then find their lowest common denominator by means of their lowest common multiple remembering to adjust their numerators accordingly before adding or subtracting.

BEDMAS = brackets, exponents, division, multiplication, adding, subtracting or FOIL = first, outside, inside, last THIS ANSWER DOESNT TELL YOU S*IT!!!!!!!!!!!!!!!!!!!

When multiplying something with exponents, you add it. When dividing something with exponents, you subtract it.
