Step-by-step explanation:
What are the roots of the equation 2x-3/x=1 step by step?
Solution: 2x-3/x=1, or
Multiply throughout by x to get
2x^2 - 3 = x, or rewrite it as
2x^2 -x - 3 = 0. (It is of the form ax^2+bx+c = 0).
The roots are x1 and x2, where
x1 = [1+(1+4*2*3)^0.5]/4. [One root is x1 = [-b+(b^2–4ac)^0.5]/2.]
= [1+(1+24)^0.5]/4
= [ 1+(25)^0.5]/4
= [1+5]/4
= 6/4 or 3/2
x2 = [1-(1+4*2*3)^0.5]/4. [Another root is x1 = [-b-(b^2–4ac)^0.5]/2.]
= [1-(1+24)^0.5]/4
= [ 1-(25)^0.5]/4
= [1-5]/4
= -4/4 or -1.
So, x = -1 or 3/2. Answer.
