Question

Write an algebraic equation for the following.

The difference of a number squared and the number is one less than four times the number.

Answer 1

let "a number" be x
then "difference of a number squared and the number" would be x^2 - x
"is" means "="
"one less than four times the number" would be 4x - 1
so you get x^2 - x = 4x - 1
