quotient
(noun)
The result of dividing one quantity by another.
(noun)
The number resulting from the division of one number or expression by another.
Examples of quotient in the following topics:
-
Logarithms of Quotients
- By applying the product, power, and quotient rules, you could write this expression as $\log_2(x^4)+\log_2(y^9)-\log_2(z^{100}) = 4\log_2x+9\log_2y-100\log_2z.$
- Relate the quotient rule for logarithms to the rules for operating with exponents, and use this rule to rewrite logarithms of quotients
-
Difference Quotients
- The difference quotient is used in algebra to calculate the average slope between two points but has broader effects in calculus.
- It is also known as Newton's quotient:
- The difference quotient is the average slope of a function between two points.
- In this case, the difference quotient is know as a derivative, a useful tool in calculus.
- Relate the difference quotient in algebra to the derivative in calculus

Dividing Polynomials
- For example, find the quotient and the remainder of the division of $x^3 - 12x^2 -42$, the dividend, by $x-3$, the divisor.
- Multiply the divisor by the result just obtained (the first term of the eventual quotient): $x^2 \cdot (x − 3) = x^3 − 3x^2$.
- For example, find the quotient and the remainder of the division of $x^3 - 12x^2 -42$, the dividend, by $x-3$, the divisor.
- Multiply the divisor by the result just obtained (the first term of the eventual quotient): $x^2 \cdot (x − 3) = x^3 − 3x^2$.
- The calculated polynomial is the quotient, and the number left over (−123) is the remainder:
-
The Remainder Theorem and Synthetic Division
- Synthetic division is a technique for dividing a polynomial and finding the quotient and remainder.
- This gives the quotient $x^2-9x-27$ and the remainder $-123$.
- As the leading coefficient of the divisor is $1$, the leading coefficient of the quotient is the same as that of the dividend:
- The result of $-12 + 3$ is $9$, so since the leading coefficient of the divisor is still $1$, the second coefficient of the quotient is $-9:$
- So the quotient must be the second degree polynomial $x^2 + 9x + 27$.

Division and Factors
- So given two polynomials $D(x)$ (the dividend) and $d(x)$ (the divisor), we are looking for two polynomials $q(x)$ (the quotient) and $r(x)$ (the $remainder)$ such that $D(x) = d(x)q(x) + r(x)$ and the degree of $r(x)$ is strictly smaller than the degree of $d(x).$
- Conceptually, we want to see how many copies of $d(x)$ are contained in $D(x)$ (this is the quotient) and then how far $D(x)$ is away from being a multiple of $d(x)$ (this is the remainder).
- Again looking at the highest degree terms, we see that $4x^2 = 2x\cdot2x$, so we write down $2x$ as the second term in the quotient and proceed as before:
- We see that the quotient $q(x)$ $3x^2+2x+6$ and the remainder $r(x)$ is $22$, so
- (Of course, the quotient will also be a factor.)

Zeroes of Polynomial Functions With Rational Coefficients
- In mathematics, a rational number is any number that can be expressed as the quotient or fraction p/q of two integers, with the denominator q not equal to zero.
- It was thus named in 1895 by Peano after quoziente, Italian for "quotient".

Basic Operations
- Rather than multiplying quantities together to result in a larger value, you are splitting a quantity into a smaller value, called the quotient.
- Calculate the sum, difference, product, and quotient of positive whole numbers
-
Negative Numbers
- Calculate the sum, difference, product, and quotient of negative whole numbers

Fitting a Curve
- The denominator is $92-\frac{1}{8}(20)^{2}=92-50=42$ and the slope is the quotient of the numerator and denominator: $\frac{23.25}{42}\approx0.554.$
