0=(0.2x*x*x-0.3x*x+0.1)(-0.1x*x*x*x*x+0.4x*x+4)+0.3
We move all terms to the left:
0-((0.2x*x*x-0.3x*x+0.1)(-0.1x*x*x*x*x+0.4x*x+4)+0.3)=0
We add all the numbers together, and all the variables
-((0.2x*x*x-0.3x*x+0.1)(-0.1x*x*x*x*x+0.4x*x+4)+0.3)=0
We multiply parentheses ..
-((+0x^8+0x^5+0x^3+0x^7+0x^4+0x^2+0x^5+0x^2+0.4)+0.3)=0
We calculate terms in parentheses: -((+0x^8+0x^5+0x^3+0x^7+0x^4+0x^2+0x^5+0x^2+0.4)+0.3), so:
(+0x^8+0x^5+0x^3+0x^7+0x^4+0x^2+0x^5+0x^2+0.4)+0.3
We do not support expression: x^8
