x 2 − 8 x + 12 = x 2 − 6 x − 2 x + 12 = x ( x − 6 ) − 2 ( x − 6 ) = ( x − 2 ) ( x − 6 )
The final factored form of x 2 − 8 x + 12 is ( x − 6 ) ( x − 2 ) . This is found by identifying two numbers that multiply to the constant term (12) and add to the linear coefficient (-8). These factors allow the expression to be expressed in a simpler form as a product of two linear expressions.
