i dont know which answer u will understand tell me the formula u have learned im a topper in 7 class

Step-by-step explanation:

Answer 2

Answer:

x= -0.511 or x= 0.338

Step-by-step explanation:

(9x^2+9)/x^2 -(9x+9)/x-52=0

=(9x^2+9-9x^2+9x-52x^2)/x^2=0

=-52x^2-9x+9=0

x=[-b+√(b^2-4ac)]/2a or [-b-√(b^2-4ac]/2a

a=-52

b=-9

c=9

x=[9+√(9*9-(4*-52*9))]/ 2*-52or 9-√(9*9+(4*-52*9))]/*2*-52

x=(9+44.192)/(-104) or 9-44.192/(-104)

=-0.511 or 0.338
