1.One root of each equation below is the same for both equations. what is this root?
a.3x^4 + 14x^3 + 8x^2=0
b.18x^4  50x^2=0
2. Find the other roots of each equation in question 1

a)
x^2(3x^2 + 14x + 8) = 0
x^2 (3x+2)(x+4) = 0
x = 0 , or x=2/3, or x = 4
b)
2x^2(9x^2  25) = 0
2x^2(x+3)(x3) = 0
x = 0 , x = 3, x = 3
