Question

Explain how to translate the phrase into an algebraic expression.

a number squared decreased by ten

Answer 1

Answer:

Let number be x

Therefore expression = x^2 - 10

Answer 2

Answer:

$x^{2}$-10

Step-by-step explanation:

“A number” is not a given number, so this will be our variable. Let “a number” be x. Since x is squared, we have to add an exponent of 2 because we are multiplying x by itself. This gives us $x^{2}$. However, “decreased by ten” indicates that $x^{2}$ is also having a quantity of ten being taken away, so we have to subtract 10 from $x^{2}$ to get the expression $x^{2}$-10.
