An equation is simplified when all like terms are combined and parentheses have been removed.

Here are some guidelines for Simplifying Expressions.

1) Remove parentheses by multiplying factors 2) Use exponent rules to remove parentheses in terms with exponents 3) Combine like terms by adding coefficients 4) Combine the constants

math 5(2+x)+3(5x+4)-(x^2)^2 math
 * EXAMPLE**

First, take of the parentheses of the equation by using the distributive property. math 10+5x+15x+12-(x^2)^2 math

Next, Multiply the exponents. math 10+5x+15x+12-x^4 math

Now, combine alike terms. We will start with the x's (make sure that they are like terms) math 10+20x+12-x^4 math (The x's cannot be combined with the other x^4 because even though they have the same variable the exponent makes them different)

Combining the constants gives, math 22+20x-x^4 math

Your done! But to make it perfect in Simplifying Equations you must make sure that it is in a certian order. You put it in You start with the largest exponent and work your way down UNTIL you get down to the end. math -x^4+20x+22 math Thats how you simplify an equation!
