Using the method of extracting common factor to calculate Using the square difference factorization factor 1 / to decompose the following formula 1. M + 2 power of a - (2b-c) 2. M power of a 3. A (x-1) + 4 (1-x) 4. (x + y + Z) - (X-Y-Z) 5. (3x + 2x-8) - (x-2x-8)

Using the method of extracting common factor to calculate Using the square difference factorization factor 1 / to decompose the following formula 1. M + 2 power of a - (2b-c) 2. M power of a 3. A (x-1) + 4 (1-x) 4. (x + y + Z) - (X-Y-Z) 5. (3x + 2x-8) - (x-2x-8)

A - (2b-c) = [a - (2b-c)] - [a + (2b-c)] = (a + 2b-c) (a-2b + C) the M + 2nd power of a - the m power of a = the m power of a (A-1) = the m power of a (a + 1) (A-1) a (x-1) + 4 (1-x) = a (x-1) - 4 (x-1) = (x-1) (A-4) = (x-1) (A-2) = (x-1) (x + 1) (A-2) (x + y + Z) - (X-Y-Z) = [x + y + Z + (X-Y -]
