Question

Solve the equation x^13-2x^12-x^11+2x^10=0 in the real number system

Answer 1

x= -1, x=1 and x=2

Explanation:

The equation is;

`x^(13) -2x^(12) -x^(11) +2x^(10) =0`

Using a graph tool to graph the equation and identify the solution you will have;

x= -1,

x=1

x=2

Check answers

when x=2

`2^(13)-2(2^(12) )-2^(11) +2(2^(10) )\\\\\\2^(13) -2^1(2^(12) )-2^(11) +2^1(2^(10) )\\\\\\2^(13) -2^(13) -2^(11) +2^(11) =0`
