Answer:
434
Step-by-step explanation:
310 times .4 (percentage) = 124 which is how much she gained, then you add that onto the original amount to find how many she has now, which is 434
X^4 - 3x^2 + 2 = 0
(x^2 - 2)(x^2 - 1) = 0
so either x^2 - 2 = 0 or x^2 - 1 = 0
so x^2 = 2 or x^2 = 1
so x = sqrt 2 , - sqrt2, 1 , -1 Answer
all the roots are real
