Still looking at how to solve these... Both are cubic polynomials? 43x^3 + 13x^2 + 18x  456 = 0 DO I divide first by x1? 2x(3x+2)^2=312 Honestly: I would graph the equations and find the roots first. I don't see them off hand.

Still having problems solving this... 2x(2x + 1)^2 = 312 I started with: 2x(2x+1)(2x+1)312 = 0 2x(4x^2+4x+1)312 = 0 8x^3+8x^2+2x 312 = 0 Now what? If you don't have to solve for x, then then you have the final answer! If you

Find the polynomials roots to each of the following problems: #1) x^2+3x+1 #2) x^2+4x+3=0 #3) 2x^2+4x5 #3 is not an equation. Dod you omit "= 0" at the end? #2 can be factored into (x+1)(x+3) = 0, so the roots are x=1 and 3.

How do you solve the rational equation: (n/n2)+(n/n+2)=(n/n^24) I know that the LCD of the equation is (n+2)(n2) because that is what you get when you factor out the n^24 in the last part of the question. I thought I did it

x^2/x+3  5/x+3=0 *Please solve the rational equation Your non use of parenthesis is annoying and most confusing. I assume you meant x^2/(x+3)  5/(x+3)=0 multiply both sides of the equation by x+3, and solve.
