DRAW A FROG HOMEWORK • IF YOU CAN DO THESE YOU ARE A SUPER MATHEMATICIAN The Distributive Property & Combining Like Terms – ( y – 5 ) = ( y )( –1 ) + ( –5 )( –1 ) = – y + 5 –( 7 – 3 x ) = ( –1 )( 7 ) + ( –1 )( –3 x ) = –7 + 3 x = –3 – 3 x ( –3 )( 1 + x )= ( –3 )( 1 ) + ( –3 )( x ) Simplify. Distribute the –3 . Simplify . Distribute the –1 . Simplify. – a = –1 • a U SING THE D ISTRIBUTIVE P ROPERTY Remember that a factor must multiply each term of an expression. Forgetting to distribute the negative sign when multiplying by a negative factor is a common error. BACK Like Terms are expressions that contain the same variable raised to the same power like 4mn and 7mn. Combine like terms. S IMPLIFYING BY C OMBINING L IKE T ERMS 4 x 2 + 2 + x 2- 6 = 11 x +y The 8x and 3x are like terms and can be combined. 8 x + 3 x + y = 4 x 2 +1 x 2 + 2 - 6 Group like terms....
