Note that algebraic expressions are mathematical expressions involving constants, variables and algebraic operations
(subtraction,addition,multiplication,division&exponentiation)
examples:
        1.) (x + 5)(x - 5)
           using distributive property you'll have
            x² - 5x + 5x - 25
            x² - 25

        2.) x²y (x + y)
           using distributive property you'll have
            x³y + x²y²
   
        3.) 6a(x + y + z)
          using distributive property you'll have
             6ax + 6ay + 6az

        4.) yz( xy² + 1)
            using distributive property you'll have
            xy³z + yz
  
        5.) ac(b+1)
            using distributive property you'll have
            abc + ac
