Use Newton's method with the specified initial approximation x1 to find x3, the third approximation to the solution of the given equation. (Round your answer to four decimal places.) 2/x − x2 + 1 = 0, x1 = 2

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

the answer is a, biohazard symbol
