Simplify (14x2−3x+2.25)+(0.75x2+2x−14).

Answer 1

To simplify the expression (14x^2 - 3x + 2.25) + (0.75x^2 + 2x - 14), we need to combine like terms and simplify.

First, let's combine the x^2 terms. 14x^2 + 0.75x^2 = 14.75x^2.

Next, let's combine the x terms. -3x + 2x = -x.

Finally, let's combine the constant terms. 2.25 - 14 = -11.75.

So, the simplified expression is 14.75x^2 - x - 11.75.
