Note #5 Objective - To factor trinomials in the form. Factoring when c is positive. Multiply. Last Terms Factor. Sum of Last Terms Product of Last Terms ( x + 2 )( x + 5 ) sum product

Factor. 1) 2) 3) ( x + 4 )( x + 5 ) (y (m 2 )( y 3 )( m 6) 4)

Factor. Show factor pairs of the constant term. 1) ( x + 6 )( x + 7 ) 2) (m 3)(m 7 ) 3) (y 4) ( k + )( k + 3)( y 12 ) ) Not Factorable 5) (x 3)( x 8)

Factoring when c is negative. Multiply. Last Terms Difference of Last Terms Product of Last Terms Factor. ( x + 6 )( x difference product 2)

Factor. 1) ( x + 4 )( x 3) 2) ( y + 5 )( y 8) 3) ( t + 2 )( t 9)
