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.

Can you pleas Solve the quadric equation step by step 4x square =13x+2 4x^2 = 13x + 2 subtract 13x and 2 from both sides 4x^2  13x  2 = 0 Now use the quadratic formula, since it does not factor.

Solve the equation using the Quadratic Formula 5xsquared+13x6=0 i think it is 2/5,3 5x^2 + 13x 6 (5x 2)(x +3)=0 You are correct. From Bob Pursley's work you can see that his solution gives +2/5 and not 2/5. The +2/5 is

How can you tell if an equation is quadratic and not linear? Quadratic equations contain a term that is squared (such as x^2). Linear equations are of the form y = mx + b, where m and b are constants. the variable in a quadratic

Hi, I am trying to solve graphing quadratic equations. One of the problems is written as x^2= 2x1. So if I wanted to put this equation in the proper quadratic equation form, would it be 2x1x^2, or x^2+2x1? I'm really not
