What is the formula of rational algebraic expression?

A rational algebraic expression (or rational expression) is an algebraic expression that can be written as a quotient of polynomials, such as x2 + 4x + 4. An irrational algebraic expression is one that is not rational, such as √x + 4.

How do you simplify math equations?

To simplify any algebraic expression, the following are the basic rules and steps:

1. Remove any grouping symbol such as brackets and parentheses by multiplying factors.
2. Use the exponent rule to remove grouping if the terms are containing exponents.
3. Combine the like terms by addition or subtraction.
4. Combine the constants.

What is mathematical equation?

In mathematics, an equation is a statement that asserts the equality of two expressions, which are connected by the equals sign “=”. The expressions on the two sides of the equals sign are called the “left-hand side” and “right-hand side” of the equation.

How to solve x – 4 (x + 3) = 0 true?

Set the next factor equal to 0 0. Subtract 3 3 from both sides of the equation. The final solution is all the values that make ( x − 4) ( x + 3) = 0 ( x – 4) ( x + 3) = 0 true.

How do you write -3x – 3x as a fraction?

Move 1 4 1 4 to the left side of the equation by subtracting it from both sides. To write x 4 x 4 as a fraction with a common denominator, multiply by x x x x. To write − 3 x – 3 x as a fraction with a common denominator, multiply by 4 4 4 4.

How to write -1 4 – 1 4 as a fraction?

To write −1 4 – 1 4 as a fraction with a common denominator, multiply by x x x x. Multiply 1 4 1 4 and x x x x. Combine the numerators over the common denominator. Factor x2 − 12−x x 2 – 12 – x using the AC method. Tap for more steps… Consider the form x 2 + b x + c x 2 + b x + c. Find a pair of integers whose product is c c and whose sum is b b.
