How would you solve the following I'm stumped..
1. 2x^2(squared)=304x
2. X^3(cubed)+8x=6x^2(squared)
Thanks!

First, set each equation equal to 0:
1. 2x^2 + 4x  30 = 0
2. x^3 + 6x^2 + 8x = 0
Try to factor when possible:
1. (2x  6)(x + 5) = 0
2. x(x^2 + 6x + 8) = 0
x(x + 2)(x + 4) = 0
Set each factor equal to 0:
1. 2x  6 = 0
x + 5 = 0
2. x = 0
x + 2 = 0
x + 4 = 0
Can you take it from here to find the solutions for x in both problems?
I hope this explanation helps. 
Yes thank you!
