use technology to approximate all reaal solutions of each equation to the nearest hundredth?

Question

x^3-2x^2+x=12

Answer 1

technology - a manner of accomplishing a task especially using technical processes, methods, or knowledge


what else are you going to use?

paste
solve(x^3-2*x^2+x=12, x);
into Maple and get the results without thinking:
There are three roots: two complex conjugates and an integer
3, -1/2+1/2*I*15^(1/2), -1/2-1/2*I*15^(1/2)

3 is obviously the real solution, so let's approximate it to the nearest hundredth:
3.00

Answer 2

x=3
