-6x3 + 4x7 - 0.8x2 + x4 - 5x5 = 4x7 - 5x5 + x4 - 6x3 - 0.8x2 = x2 (4x5 - 5x3 + x2 - 6x - 0.8)
What is the additive inverse of the polynomial –9xy2 + 6x2y – 5x3?
An expression. It can be factored out slightly too: 2x6 + 5x3 - 7x4 = x3(2x3 - 7x + 5)
X4=
X4.
-6x3 + 4x7 - 0.8x2 + x4 - 5x5 = 4x7 - 5x5 + x4 - 6x3 - 0.8x2 = x2 (4x5 - 5x3 + x2 - 6x - 0.8)
None. 5x3 is a pure number, not a length.
(4x^4 −5x^3 +6x+11)−?=x^4 −x^3 −x^2 −3x+2
