Answer:
[tex]x^{2}-(2x+4x)[/tex]
Step-by-step explanation:
Let
x-----> the number
we know that
The expression "The sum of twice a number and four times a number" is equal to
[tex](2x+4x)[/tex]
The expression "The number squared" is equal to the algebraic expression
[tex]x^{2}[/tex]
therefore
The complete expression
"The sum of twice a number and four times a number subtracted from the number squared" is equal to the algebraic expression
[tex]x^{2}-(2x+4x)[/tex]
