How do you write x is greater than 2?
x > 2, “The number is greater than 2.” x < 2, “The number is less than or equal to 2.” x > 2, “The number is greater than or equal to 2.” When you multiply or divide an inequality by a negative number, you must “flip” the sign to make the statement true.
Is x greater than or equal to?
For example, if x ≥ 3 is given, it means that x is either greater than or equal to 3….Greater Than or Equal To Application.
| Symbol | Example | Meaning |
|---|---|---|
| Greater than or equal to, ≥ | x ≥ 2 2 ≥ x ≥ −1 | The value of x is greater than or equal to 2. The value of x is between -1 and 2 inclusive of both values. |
What is the solution of the inequality X² 9 0?
This is simply solving a quadratic, which we do by factorising and equating each term in brackets to zero, i.e.:x2 – 9 = 0This is the difference of two squares, so the factorisation should be relatively familiar. (x+3)(x-3) = 0Therefore x= – 3 or x = 3.

What are the steps for solving inequalities?
To solve an inequality use the following steps:
- Step 1 Eliminate fractions by multiplying all terms by the least common denominator of all fractions.
- Step 2 Simplify by combining like terms on each side of the inequality.
- Step 3 Add or subtract quantities to obtain the unknown on one side and the numbers on the other.
What are the roots of the quadratic equation √ 2×2 9 9?
Correct option is (B) x = ± 6 ± 6.
What are roots of quadratic equation?
Roots of Quadratic Equation. The values of variables satisfying the given quadratic equation are called its roots. In other words, x = α is a root of the quadratic equation f(x), if f(α) = 0. The real roots of an equation f(x) = 0 are the x-coordinates of the points where the curve y = f(x) intersect the x-axis.
