The sentence "5 is subtracted from the square of a number" represented as an algebraic expression is: [tex]x^{2} - 5[/tex]

  • Let the number be x.

In this exercise, you're required to write an algebraic expression to represent the word problem (sentence). Also, the number would be denoted by the letter x and no need for further simplification of the algebraic expression.

Translating the word problem (sentence) into an algebraic expression, we have;

Square of a number (x) = [tex]x^{2}[/tex]

Subtracting 5 from the the square of x, we have;

[tex]x^{2} - 5[/tex]

The expression is given by:

[tex]x^2 - 5[/tex]

------------------------------

  • As the number is unknown, the problem states that we should call it x.
  • The square of 1 is [tex]1^2 = 1[/tex], of 2 is [tex]2^2 = 4[/tex], and so on, thus the square of x is [tex]x^2[/tex].
  • 5 subtracted from 6 is [tex]6 - 5 = 1[/tex], from 7 is [tex]7 - 5 = 2[/tex], and so on, thus, 5 subtracted from the square of the number is [tex]5 - x^2[/tex], which is the desired expression.
