Question

solve for the values of x. (1/x)+x=4

Answer 1

1/x + x = 4 -> (1+x^2)/x = 4 -> 1 + x^2 =4x

Can you do it now?

Answer 2

yea sure

Answer 3

quadratic equation?

Answer 4

very good you guessed that right medals for you

Answer 5

wow.. this problem was one year ago since it was posted!

Answer 6

X=(3.732050808,0.267949192)

Answer 7

i still dont understand

Answer 8

first add 1/x and x---> x times x + 1 = 1+x^2 all over x

Answer 9

then your new equation now is (1+x^2)/x=4

Answer 10

then multiply both sides by x to cancel out the fraction form of (1+x^2)

Answer 11

so the answer must be 1+x^2=4x

Answer 12

transpose 4x and change the sign. -4x+x^2+1

Answer 13

then finally use the quadratic equation.

Answer 14

x=-b+sqrt(b^2-4ac)/2a. ?

Answer 15

yes. a= 1, b= -4, c=1
