(1/16x^4 +3/8x^3 +1/8x^2-1)+ (-9/16x^4 +7/8x^2 -1) Can you please help me solve this problem? Thank you.
Since it is not an equation, I cannot solve it for you, but I can help you to simplify it.
Get rid of the fractions by multiplying everything by 16.
(x^4 + 6x^3 + 2x^2 -16) + (-9x^4 + 14x^2 - 16)
Combine like terms.
