What are the roots of the polynomial equation 3x^4+12x^2=6x^3
Dominik [7]
Factor the equation to give
3x^4+12x^2=6x^3
3x^4+12x^2-6x^3=0
x^2(3x^2+12-6x)=0
By the zero product property, either x^2=0 or (3x^2+12-6x)=0 or both.
If x^2=0, then x=0
if (3x^2+12-6x)=0, we use the quadratic formula to solve for x
where x=1 ± √ (3) i

Answer: the roots of <span>3x^4+12x^2=6x^3 are {0 (multiplicity 2), 1+&radic;3 i, 1-&radic;3 i}</span>

Kendra flips a fair coin two times. What is the probability that she will flip tails both times?
wolverine [178]

Answer: 1/4 or 25%

Step-by-step explanation:

The chance of flipping tails is 1/2, so you multiply 1/2*1/2 (for the 2 flips) to get 1/4 (1/2^2=1/4).
