A line can only cross another line in at most one place, so there can be at most one **solution** (x=3). A parabola, though, curves, so it can cross the x axis in **two** places. So **if** you **have** an **equation** like x^**2** + 5x + 6 = 0, it can **have two solutions**.

Sometimes we use the **symbol** ∞, which means **infinity**, to represent **infinite solutions**.

## Q. Does the absolute value of x equal X?

More Formal. Which says the **absolute value of x equals**: **x** when **x** is greater than zero. 0 when **x equals** 0.

## Q. What is the R symbol in math?

R = **real numbers**, Z = integers, N=natural numbers, Q = rational numbers, P = irrational numbers.

## Q. How do you know if an equation has two Solution?

A **quadratic equation** has two solutions. Either two distinct real solutions, one double real solution or two imaginary solutions. All methods start with setting the equation equal to zero.

## Q. How do you solve problems with two variables?

In a **two**–**variable problem** rewrite the equations so that when the equations are added, one of the **variables** is eliminated, and then **solve** for the remaining **variable**. Step 1: Multiply equation (1) by -5 and add it to equation (**2**) to form equation (3) with just one **variable**.

## Q. What is a quadratic equation with 2 solutions?

The **discriminant** is negative, so the quadratic equation has two complex solutions. The quadratic equation x2 – 4x + 10 = 0 has two complex solutions. Suppose a quadratic equation has a **discriminant** that evaluates to zero….

x = −1 + 2i | x = −1 – 2i |
---|---|

1 – 4 – 2 = −5 | 1 – 4 – 2 = −5 |

−5 = −5 | −5 = −5 |

👉 Learn how to solve multi-step equations with variable on both sides of the equation. An equation is a statement stating that two values are equal. A multi…
