Example: to rationalize fracsqrt2-sqrt31-sqrt2/3 type r2-r3 for numerator and 1-r(2/3) for denominator.Just "factor out" the number 3 by dividing each term by 3 to get your simplified equation.This means that all x2 terms can be combined with other x2 terms, that all x3 terms can be combined with x3 terms, and that all constants, numbers that are not attached to variables, such as 8 or 5, can be added up, or combined.Look at the coefficients of all of the terms (the numbers before the variables, or the constants) and see if there is a number that you can "factor out" by dividing each term by that number.An algebraic expression is a mathematical phrase that can contain numbers and/or variables.Here's how to do it: Here's how you solve for the absolute value by isolating the absolute value and then removing it: 4x x x 2 14 4x x 12 x 3 Now, solve again by flipping the sign of the term on the other.Also be careful when you write fractions: 1/x2 ln(x) is 1/x2 ln(x) and 1 x2 ln(x) is 1 x2 ln(x).
