Question:

25(a+b)² - (a-b)²

Answer:

24a²+52ab+24b²

Step-by-step explanation:

25(a+b)² - (a-b)² = [5(a+b)]² - [a-b]²

                           =[5(a+b)+(a-b)][5(a+b)-(a-b)]

                           =[5a+5b)+(a-b)][5a+5b)-(a-b)]

                            =[5a+5b+a-b][5a+5b-a+b]

                            =[6a+4b][4a+6b]

                            =6a[4a+6b] + 4b[4a+6b]

                            =24a²+36ab+16ba+24b²

                            =24a²+52ab+24b²
