Q: A: ### Quick Answer

**Quadratic equations govern many real world situations such as throwing a ball, calculating certain prices, construction, certain motions and electronics.** They are most often used to describe motion of some sort.

An equation is quadratic if it is of "order 2;" that is, an equation is quadratic if the highest power in the equation is 2. Therefore, x^2 and any variations of it are quadratic equations. For example, if a ball is thrown straight from 3 meters above the ground at a velocity of 14 meters per second, this allows the construction of an equation. The equation is quadratic because half of the gravitational velocity, 5t^2, is subtracted from the other constants. By setting the equation equal to zero, two solutions can be acquired. The interesting part is that these solutions show when height is equal to zero. In other words, solving this yields what time the ball was on the ground after being thrown. This information can then be used to acquire even more information, such as how long the ball was in the air, when it reached its highest point and where the ball is at any time after being thrown. The same method is employed in other situations where quadratics are involved.

## What is the meaning of the quadratic function: "f(x) = ax2 + bx + c"?

A:The quadratic function "f(x) = ax2 + bx + c" is the standard form for quadratic equations. F(x) is representative of the output, and x is the variable, also called the unknown. A, b and c in the equation are known values.

Full Answer >**Linear equations may be solved by isolating the variable or variables.**Solving linear equations involves undoing whatever operations have been done to the variable and putting the variable alone on one side of the equal sign.Filed Under: - Q:
## How do you solve rational equations?

A:To solve rational equations, use the common denominator to resolve all the fractions. Removing the denominators makes it much easier to deal with the remaining terms, converting the problem into a simpler equation.

## What are the steps in solving trinomial equations?

A:Solving trinomial equations is a matter of determining the degree of the trinomial factoring according to the degree and the terms themselves and by then verifying that the factors found are the actual roots of the equation. These roots are the solutions to the equation.
