How do you simplify variable expressions in algebra?

Answer by  worker7041 (64)

You factorize the expression by taking out a common factor. E. g. ax^3 + bx^2y + cx = x * (ax^2 +bxy + c) You take the highest common factor and write the expression as a multiple of that factor, as shown above. The same principle applies to other variable expressions.

Algebraic expressions are expressions containing variables and they are usually simplified by combining like terms. For example 6x² + 9x - (3x + 15x² + 7x³) = 6x²+9x-3x-15x²-7x³ = -9x²+6x-7x³. If multiple terms are involved, the order of operations must be employed when evaluating expressions parentheses,exponents(powers&roots),multiplications/divisions,additions/subtractions working from left to right.
