Sederhanakanlah (2x + 9) – (4x – 3)

( a − 2 b ) ( 2 a − b ) ( a + 2 b ) = ( 2 a − b ) ( a 2 − 4 b 2 ) = 2 a 3 − 8 a b 2 − a 2 b + 4 b 3 = 2 a 3 − a 2 b − 8 a b 2 + 4 b 3

To simplify the expression ( a − 2 b ) ( 2 a − b ) ( a + 2 b ) , we first multiply the first two binomials to get 2 a 2 − 5 ab + 2 b 2 , and then multiply this result with ( a + 2 b ) to obtain the final result 2 a 3 − a 2 b − 8 a b 2 + 4 b 3 .

= (2x + 9) - (4x - 3)= 2x + 9 - 4x + 3= 2x - 4x + 9 + 3= -2x + 12[tex]\boxed{ \red{ \boxed{\pink{\mathcal{M \frak{ ilana} \purple{ \tt01}}}}}} [/tex]
