What is a quadratic expression?
A quadratic expression is an expression which is written in the form ax2+bx+c, where a, b, and c represent constants, x represents a variable, and a is not equal to 0.
When the following expression is written in simplest form what is the coefficient of the variable term -2.5y plus 8y - 10.5y?
-5
Is X-8 a first degree binomial?
Any expression with form Ax+b where a and b are constants are first degree binomials.
How do you write an expression in quadratic form?
Write an expression consisting of up to three terms:One term in which the key variable is squared,one term with a multiple of the variable, anda constant.The first of these MUST be present. The three terms must be added or subtracted.
How do you know if an equation is exponential?
Basically, in an exponential expression (or equation) you have the independent variable in the exponent. For example: 5 times 10x The general form of an exponential function can be written as: abx or: aekx where a, b, and k are constants, and e is approximately 2.718. Note that just having a power doesn't mean you have an exponential equation. For example, in x3 the variable does NOT appear in the exponent, so it is not an exponential expression.

-5
What is x when in an expression it is the form of x?
'x' is a fixed but unknown amount. It is not a VARIABLE!!!!
When the following expression is written in simplest form what is the coefficient of the variable term -1.5r plus 6r and ndash 12.2r?
To find the coefficient of the variable term, we need to combine like terms. The coefficient of the variable term -1.5r is -1.5. The coefficient of the variable term 6r is 6. The coefficient of the variable term -12.2r is -12.2. Thus, when combined, the coefficient of the variable term is -1.5 + 6 - 12.2, which simplifies to -7.7.
What is the meaning of variable in algebraic expression?
Variable is any letter used in an algebraic expression, and can vary (change form) to be any number, and one variable means the same number in any single algebraic expression. Usually algebra is simplifying the expression or equation until you know what the variable is equal to.
What is an expression of second degree?
An expression of the second degree can be any kind of expression, the most popular being a quadratic polynomial of the form ax^2 + bx + c.
What is this 3x equals 2y plus 7 in standard form?
It is an expression in two variable: it is NOT an equation. There is no standard form for expressions.
What is the standard form of the expression I2 plus 1?
It is 2I + 1. The coefficient is put before the variable.
What is the expression for x equals 3 and y equals 6?
A mathematical expression in its' most simplistic form, merely assigns a value to a variable. Don't confuse an expression with an equation. An equation requires a solution. An expression cannot be "solved". It only allows you to determine the value of a variable. This is the expression in words "x is equal to 3" (X is the variable which is equal to the constant number 3) This is the expression in numbers "x=3" The expression in words "y is equal to 6" (Y is the variable which is equal to the constant number 6) The expression in numbers is "y=6" I hope you understand now.
Can a term in an algebraic expression be zero?
Yes they can, for example quadratic expressions are often written in the form, ax^2+bx+c, where x is a variable, and a,b,c are constants. If you have an expression such as 5x^2 - 3, then clearly a=5, c=-3 and b=0
Is X 8 a first degree binomial?
Any expression with form Ax+b where a and b are constants are first degree binomials.
Is X-8 a first degree binomial?
Any expression with form Ax+b where a and b are constants are first degree binomials.
