Question

if x2+1/x=5/2,find the value of x3+1/x3

Answer 1

Step-by-step explanation:

(x+1)=3x resolves with easiness as: 2x=1=2×.5

[math]x^2+1=3x[/math] however, we observe this does not atall result same easiness of resolve as 1, and we get to Figure 3 as: (Example1×(x OR 1)) To share that Same Resolve as Figure 1 must also equal 3x(y OR 1) with something more alike [math]2xy+x=xy+2x=3xy=x^2+1[/math] via y=1 onsets that a Factor is thereat via (y or 1)=y=1 has Equality of the Two Options. And we know .5 cannot equal 1, so we know x is not equal 1 nor .5 within status of Parenthetical Shift (See 8 below)
