Verified answer
Yes. Any number, or expression, is equal to itself. An equation such as:x + 5 = x + 5
is true for ANY value of "x".

What is the difference between a polynomial and a quadratic equation?
A quadratic equation is of degree 2, that is, the highest power is 2. A polynomial is not an equation, however, you can convert it into an equation by setting the polynomial equal to zero for example. A polynomial EQUATION can be of any degree: 1, 2, 3, 4, etc.
What are the roots of a parabola?
I think you are talking about the x-intercepts. You can find the zeros of the equation of the parabola y=ax2 +bx+c by setting y equal to 0 and finding the corresponding x values. These will be the "roots" of the parabola.
How do you find the maximum or minimum point of a parabola?
You set the derivative equal to zero and solve the equation. For example y = x^2 + 5x +7 is the equation of a parabola. dy/dx = 2x +5. Setting 2x +5 = 0 then x = -5/2. When x = -5/2 y = 3/4. This is the minimum. We know it's a minimum and not a maximum because when x is large y is large.
Can you solve this polynomial equation by factorization and examine the curvature of the function the equation function is X squared plus 4x minus 5 equals 0?
For the equation: x2+4x-5 = 0 Factoring yields: (x+5)(x-1) = 0 The zero identity states that setting these factors individually equal to zero will yield valid solutions to this equation. x+5 = 0, x = -5 x-1 = 0, x = 1 So the values x=-5 and x=1 solve this equation. For the mathematical function: y = x2+4x-5 The derivatives for this function are as such: y' = 2x+4 y'' = 2 The second derivative is a constant positive number (2), so it is always positive. Since the second derivative is always positive, its curvature is always concave upward.
How do you find the x value?
By moving all other values to one side and setting it equal to X. For instance, x-12=24. To find the "x" value, add 12 to both sides of the equation which will result in x=36. We know that x=36 is true because when we "plug-in" or "substitute" every "x" in the original equation with the value "36", we should get matatically true statements. For instance 36-12=24 is a true statement.

How do you find the value of x when there is no equal sign in the equation?
You cannot explicitly find the value of x without an equal sign, as an equation without an equals sign is an algebraic expression. However, we can turn your expression into an equation by adding in an equals sign, but setting the value to a variable. For example, 2x+5=y, or 5x2-4x=y. You can solve for x like that. The phrase "... there is no equal sign in the equation ..." is a meaningless description. Without an 'equal' sign, there is no equation.
What is the value of x in 4x plus 15?
You can't answer this question without setting that expression equal to something. Right now, your equation reads 4x+15=?, essentially created a system of two variables with only one equation, which is unsolvable.

How do you calculate roots?
The roots of an equation in two variables is calculated by setting the dependent variable, y, equal to 0 and then solving the resulting equation for the independent variable, x. The procedure for solving the equation in x will depend on the nature of the equation.

What is the xintercept of y2x 5?
As written this is not a graphable thing. I does not represent a graphable equation because there is no "=" sign. Whatever the equation might be, the x intercept is found by setting y=0, which leaves you with an equation for x, which is the intercept.
Why is the denominator set to zero to graph a rational expression?
When the denominator is equal to zero, the expression is undefined. Close to those places, the expression tends towards plus infinity, or minus infinity. In other words, setting the denominator to zero will tell you where there are vertical asymptotes.
What does the Canadian expression 'the dog' mean?
As in "f*cking the dog" - the act of being lazy, typically used in a workplace setting.
Greek for Cheers?
The Greek expression for cheers is Yama's. This is used when drinking in a group setting. Everyone raises their glasses and says Yama's.
How do you write an equation that works in forward and reverse?
You can write an equation that works in forward and reverse by setting the same variables on either side. Alternatively you can set offsetting variables on each side which will also create the same results.
How do you find all the zeros of a function?
You could try setting the function equal to zero, and finding all the solutions of the equation. Just a suggestion.
