How many integers x satisfy the equation
(x2 - 2x + 2)x2 + x = 1
Read Solution (Total 7)
-
- (x^2-2x+2)*x^2 + x = 1
=> [(x-1)^2+1]*x^2 + x = 1
for any integral values of x LHS of eqn always greater than 1
NO INTEGRAL SOLUTION - 10 years agoHelpfull: Yes(34) No(10)
- (-3*2- 2(-3) +2) * 2 + (-3)
(-6+6 +2)* 2 (-3)
2*2(-3)
4-3=1
hence x= -3 . - 10 years agoHelpfull: Yes(6) No(21)
- 0.5916164 but this is float so no integers x satisfy the equation.

- 1 integer can satisfy that euation
- 10 years agoHelpfull: Yes(1) No(1)
- (x^2-2x+2)x^2+x=1
(x^4-2x^3+2x^2)+x=1
for any value of x it will return greater than 1 - 10 years agoHelpfull: Yes(0) No(0)
- no integer solution.... L.H.S for any integer value would be always greater than 1
- 10 years agoHelpfull: Yes(0) No(0)
- I think it may be 4 because degree of equation is 4
- 10 years agoHelpfull: Yes(0) No(2)
