Factor the expression: [tex]x^2 - 9x + 8[/tex].

x 2 − 9 x + 8 = x 2 − x − 8 x + 8 = x ( x − 1 ) − 8 ( x − 1 ) = ( x − 8 ) ( x − 1 )

x 2 − 9 x + 8 = x 2 − x − 8 x + 8 = x ( x − 1 ) − 8 ( x − 1 ) = ( x − 1 ) ( x − 8 )

To factor the expression x 2 − 9 x + 8 , we find two numbers that multiply to 8 and add up to − 9 , which are − 1 and − 8 . The expression can be factored as ( x − 1 ) ( x − 8 ) . This can be verified by expanding the factors to yield the original expression.
