4. Hindi maayos yung given kaya hindi ko masolve

5. Hindi maayos yung given kaya hindi ko masolve

Solution:

1. ( x + 4 ) ( x - 3 ) - use foil method

   x² + 4x - 3x - 12

   x² + x - 12

2. ( 3m + 2 )² - use the exponent on both

   9m² + 4

3. ( x + 4 ) ( x - 4 ) - use foil method

   x² + 4x - 4x - 16

   x² - 16
