How to factorize x^4 + x^3 + 2.01 x^2 + 0.01 x + 0.01 = 0?

[logix88]

I need to get this into (x^2+ x + const) * (x^2+ x + const) format, the answer for this equation is (x^2+x+2)*(x^2+0.0025x+0.005)... I don't know how to get there, NEED HELP EXAM DAY AFTER!

Hi logix88!

I don't get it …

(x²+x+2)*(x²+0.0025x+0.005) quite obviously starts x⁴ + 1.0025x³ + … , not x⁴ + x³ + …

it is correct to 2dp (decimal places)

(x^2+x+2)*(x^2+0.0025x+0.005) is also clearly not in (x^2+ x + const) * (x^2+ x + const) format.
