The video tutorial explains how to translate verbal statements into algebraic expressions using the variable x. It covers two examples: the first involves finding the sum of the square of a number and two times the number, resulting in the expression x squared plus 2x. The second example involves finding the quotient of 10 more than the cube of a number and the number itself, resulting in the expression (x cubed + 10) / x. The tutorial emphasizes understanding key terms like 'sum' and 'quotient' and how they relate to algebraic operations.
