(x + y)3 + (x - y)3 = (x3 + 3x2y + 3xy2 + y3) + (x3 - 3x2y + 3xy2 - y3)

= 2x3 + 6xy2 = 2x*(x2 + 3y2)

Q: What is the answer to x plus y to 3rd power plus x minus y to 3rd power?

simplified it would equal: 24x to the third power - x to the second power - x to the sixth power - 34

The question contains an expression, not an equation (nor inequality). An expression cannot be solved. Without the value of x, it cannot be evaluated. And, since the numerator and denominator have no common factor, it cannot be simplified. You need to consider what exactly it is that you want a resubmit a question that makes sense.

(-2)^4 = -2 x -2 x-2 x-2 = +16 ( a minus times a minus is plus)

Organize this expression into groups of like terms, so that it is easy to combine.7x^2 - 8x + 2x - x^3 + 9 - 8Answer:7x^2 - 6x -x^3 + 1

It is a polynomial expression in x. What about it?

Infinity.

(x - 7) is.

Would you mind typing it out for me? I don't quite understand exactly what you are asking. For example, x to the second power minus 4x over x to the second power minus 16 would be... x^2-4x/x^2-16 Do you mind typing it out like that? Because what you wrote makes no sense at all.

14x squared minus 7x to the 3rd power can be factored to 7x2(2-x).
