An inequality is similar to an equation, in that it compares two expressions. But in an equality, instead of an equal sign, you would usually use one out of the following inequality symbols:* less than * less than or equal * greater than * greater than or equal
It can tell you three things about the quadratic equation:- 1. That the equation has 2 equal roots when the discriminant is equal to zero. 2. That the equation has 2 distinctive roots when the discriminant is greater than zero. £. That the equation has no real roots when the discriminant is less than zero.
Inequalities have greater than, less than, greater than or equal to, or less than or equal to signs. Equations have an equal sign.
< > = Greater than , less than and equal too
Those two quantities are equal.
If the "comparison symbol" is the equal sign, it is called an "equation". If the symbol is less than, greater than, less-than-or-equal, or greater-than-or-equal, it's called an "inequality".
If there is an equal sign, it is called an equation; if there is a less-than, a less-than-or-equal, a greater-than, or a greater-than-or-equal sign, an inequality; if there is none of these, an expression.
3x = 114 is an equation because it states that two expressions are equal to each other, whereas an inequality would involve a greater than, less than, greater than or equal to, or less than or equal to sign.
In an equation, what is to the left of the equals sign equals what is to the right. In an inequality, the left side is either less than, greater than, less than or equal to, or greater than or equal to the right side.
It is an inequality.
Same as it is.
In the same way that a diagonal line through the equals symbol changes equals (=) to does not equal (≠), a near-vertical line through the greater than symbol (>), changes it to not greater than. Unfortunately I cannot find it in my symbols set. One alternative, of course, is to change the equation around: x not greater than y is the same as x less than or equal to (≤) y. When inverting the equation in this fashion, you do need to remember to add = if it was not there and remove it if it was. ie not (greater than) is the same as less than or equal to not (greater than or equal to) is the same as less than not (less than) is the same as greater than or equal to not (less than or equal to) is the same as greater than
You can use the Not function or the <> operator, which is the < and the > beside each other. To see if the values in A1 and A2 are not equal to each other, you can type: =A1<>A2 or =Not(A1=A2) In each case they will either give you TRUE if they are not equal or FALSE if they are equal, in the cell that you enter the formula into.

The line is dotted when the inequality is a strict inequality, ie it is either "less than" (<) or "greater than" (>). If there is an equality in the inequality, ie "less than or equal to" (≤), "greater than or equal to" (≥) or "equal to" (=) then the line is drawn as a solid line.
A number is an expression. It is not an equation, or an inequality, since it doesn't have an equal sign, or an inequality (greater than, less than, etc.) sign.
If the discriminant of the quadratic equation is equal or greater than zero it will have 2 solutions if it is less than zero then there are no solutions.
