To find the solutions of x in a quadratic equation.
y=b+x+x^2 This is a quadratic equation. The graph is a parabola. The quadratic equation formula or factoring can be used to solve this.
The multiplicative property of equality. Multiply each side by -1/3.
An "extraneous solution" is not a characteristic of an equation, but has to do with the methods used to solve it. Typically, if you square both sides of the equation, and solve the resulting equation, you might get additional solutions that are not part of the original equation. Just do this, and check each of the solutions, whether it satisfies the original equation. If one of them doesn't, it is an "extraneous" solution introduced by the squaring.
The Rackett equation is used to predict the density of a pure liquid vs temperature based on its critical properties. One density value is required to calculate the Rackett constant in the equation, then the critical properties Tc, Vc, and Pc are used to estimate new density values as the temperature changes.
The measures of two angles in a triangle are shown in the diagram. Which equation can be used to find the value of x?
The answer is; 54.6 But I used my TI-84 to get that answer and I can not remember how to do these.
It is a certain type of equation used in Algebra. It uses letters to replace numbers and the aim of cracking the equation is to find the value of the letter. Such as: 4b+2=26 ....you would need to find the value of 'b'. -2( 4b= 24 )-2 ( b=6 )divided by 4 I've just solved the equation.
The number 3 equals x when it has the same value in an equation. This is used to help solve a specific problem in math where certain variables are unknown.
An equation that is used to find a answer that deals with algebra
The equation of line can be easily made if the slope and y-intercept are known, in the form of y equals mx plus b, where m is the slope and b is the y-intercept. The quadratic equation may need to be utilized if the previous equation cannot be used.
One equals is used in an equation which is true, such as 5 + 3 = 8 Equals equals is used in computer programming as a question as to whether 2 things are equal. Like If x == 4 perform this operation ... If you are referring to 'C' language programming: A single equal sign is an assignment, a double equal sign is a comparison. a = 7; /* An assignment. You are assigning the value of 7 to the variable called 'a' */ if (a == 7) /* A comparison. You are checking if the variable 'a' has the value of 7 */

It is an equation used to anwer an absolute value inequality.
"n", as well as other letters, are used as variables. They can contain any value; quite often, you need to find out what value you should replace to make an equation valid. For example, in: n + 1 = 4 In this case, if you replace "n" with "3", the equation will be satisfied (true); for any other value it won't.

Linear equations are used to find the value of missing numbers. They are also used to find the relation among the missing numbers. For example= x+3=4 x=4-3 x=1
