WebSolution: To solve this, we need to use the following algebra identities: (a + b) 2 = a 2 + 2ab + b 2 (a - b) 2 = a 2 - 2ab + b 2 Adding the above two formulas we have: (a + b) 2 + (a - b) 2 = a 2 + 2ab + b 2 + a 2 - 2ab + b 2 (a + b) 2 + (a - b) 2 = 2a 2 + 2b 2 Here we have a = 7x and b = 4y. Substituting this in the above expression we have:
