The solutions to the equation 6x^2 + 10x = 4 - 10x - 6x^2 can be written in the form x=p+-sqrtQ/R where P and R are relatively prime integers and R>0. What is the product PQR ? 

 

 

This is a HW problem. Just give me basic steps and ill try to solve it from there....

If i can, just give me more hints, or the lazy option is to just give me the solution and watch me try to read your solution.🤨🧐🤓😎

Just take it all to one side 

then solve it with the quadratic equation.

From there it shouldn't be hard.

 

I have not done it so if there are problems that i have not noticed then you can let me. or others here, know.

 6x^2 + 10x = 4 - 10x - 6x^2     rearrange as

 

12x^2 + 20x - 4  = 0           divide through by 4

 

3x^2 + 5x - 1 = 0

 

Using the quad formula

 

-5 ±√[ 5^2 - 4(3)(-1) ]                               -5   ±√ [ 37]

______________________  =              ___________

             2 (3)                                                6

 

P =  -5      Q  = 37      R  =  6

 

You should be able to evaluate PQR
