Factorization of Algebraic Exp...

We know that the product of 5x² and 2x-3y = 5x²(2x-3y) = 10x³-15x²y. we say that 5x² and 2x-3y are factors of 10x³-15x²y. We write it as 10x³-15x²y = 5x²(2x-3y).

Similarly the product of 3x+7 and 3x-7 = (3x+7)(3x-7) = 9x²-49; we say that 3x+7 and 3x-7 are factors of 9x²-49. we write it as 9x²-49 = (3x+7)(3x-7). Thus, when an algebraic expression can be written as the product of two or more expressions, then each of these expressions is called a factor of the given expression. Factorization of algebraic means to obtain two or more expressions whose product is the given expression.
