Question

X-1/x=3,x not equal 0 find x

Answer 1

x + 1x = 3⇒x2 + 1 = 3x⇒x2 − 3x + 1 = 0We have, a = 1, b = −3, c = 1Now, D = b2 − 4ac = (−3)2 − 4(1)(1) = 9 − 4 = 5 >0So, the solution of the given equation is, x = −b±D√2a⇒x = 3±5√2⇒x = 3+5√2 and x = 3−5√2

Answer 2

Answer:

x = -1/2

x-1/x=3

x-1=3x

-1=2x

x=-1/2
