Question

The sum of twice a number and four times a number subtracted from the number squared

Answer 1

`x^(2)-(2x+4x)`

Explanation:

Let

x-----> the number

we know that

The expression "The sum of twice a number and four times a number" is equal to

`(2x+4x)`

The expression "The number squared" is equal to the algebraic expression

`x^(2)`

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

`x^(2)-(2x+4x)`
