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!

I don't get it …
(x2+x+2)*(x2+0.0025x+0.005) quite obviously starts x4 + 1.0025x3 + … , not x4 + x3 + …
This equation can be factorized by grouping the terms and using the factoring techniques for polynomials. Start by factoring out the greatest common factor, in this case x, to get x(x^3 + x^2 + 2.01x + 0.01) = 0. Then, factor the remaining polynomial using techniques such as grouping, factoring by grouping, or synthetic division.
No, the quadratic formula can only be used to solve equations in the form ax^2 + bx + c = 0. This equation has a degree of 4, therefore it cannot be solved using the quadratic formula.
Yes, there are several techniques specifically for factorizing quartic equations, such as grouping, factoring by grouping, and the AC method. It is important to also look for common factors and use the techniques of factoring by grouping or synthetic division.
This equation has four possible solutions, since it is a quartic equation. However, not all solutions may be real numbers. Some solutions may be complex numbers.
The coefficients 2.01 and 0.01 are important in determining the factors of this equation. They affect the combinations of factors that can lead to the given equation, and can make the factoring process more complex. It is important to consider all coefficients when factoring a polynomial equation.
