First, you subtract the equations. (3x^2-2x+5) - (x^2+3x-2) so you get 3x^2 - 2x + 5 - x^2 - 3x + 2. This leads you to 2x^2 - 5x + 7. If you multiply that by 1/2 x^2, you get x^4 - 5/2(x^3) + 7/2(x^2)

erica [24]

Answer:

Contradictrion

Step-by-step explanation:

x + 65 -x =289

Then combine like terms.

65 = 289

There are no values of x that make the equation true. The input is a contradiction.
