Factoring in Algebra - Math is Fun

WebFactoring (called " Factorising " in the UK) is the process of finding the factors: It is like "splitting" an expression into a multiplication of simpler expressions. Example: factor 2y+6 Both 2y and 6 have a common factor of 2: 2y is 2×y 6 is 2×3 So we can factor the whole expression into: 2y+6 = 2 (y+3) So 2y+6 has been "factored into" 2 and y+3 WebIn Java, Math.pow ( ) function returns the value of the first argument raised to the power of the second argument.
