Factoring in AlgebraFactors
Numbers have factors:
And expressions (like <span>x2+4x+3</span>) also have factors:
Factoring
Factoring (called "Factorising" in the UK) is the process of finding the factors:
Factoring: Finding what to multiply together to get an expression.
It is like "splitting" an expression into a multiplication of simpler expressions.
<span>Example: factor 2y+6</span>
Both 2y and 6 have a common factor of 2:
<span>2y is 2 × y6 is 2 × 3</span>
So you can factor the whole expression into:
2y+6 = 2(y+3)
So 2y+6 has been "factored into" 2 and <span>y+3</span>
