a 2 + 11 a + 18 = a 2 + 2 a + 9 a + 18 = a ( a + 2 ) + 9 ( a + 2 ) = = ( a + 2 ) ( a + 9 )

Anonymous · Answer

The quadratic expression a 2 + 11 a + 18 can be factored into ( a + 9 ) ( a + 2 ) . This is achieved by finding two numbers (9 and 2) that multiply to 18 and add to 11. Thus, the final factored form is ( a + 9 ) ( a + 2 ) .
