Write an expression containing x2-terms, x-terms, and constants. the x2-terms ahould combine to 2x2, the teerms ahoult subtract to 3x, and the constants should sum to 3

We can write many expressions in which terms will combine to , the x terms will subtract to 3x and the constant will sum upto 3.

Let us write such an expression.

Upon combining like terms we will get,

Therefore,  is our desired expression.
