+%28a-%282b-c%29%29%28a%2B%282b-c%29%29 step 1

+%28a-2b%2Bc%29%28a%2B2b-c%29+ step 2

+a%2Aa%2B2b%2Aa-c%2Aa-2b%2Aa-2b%2A2b-2b%2A%28-c%29%2Bc%2Aa%2Bc%2A2b-c%2Ac+ step 3...multiply

+a%5E2%2B2ab-ac-2ab-4b%5E2%2B2bc%2Bac%2B2bc-c%5E2+



+a%5E2-4b%5E2%2B4bc-c%5E2+.....you can have this as an answer, or

+a%5E2-4b%28b-c%29-c%5E2+
