Question

Roots of quadratic equation 9x2
-15x +6 =0 by the method of completing the square are

Answer 1

Step-by-step explanation:

9x^2-15x+6=0

9x^2-15x=-6

9x^2/9-15/9x=-6/9

x^2-15/9x=-6/9

on adding (15/18)^2on both sides

x^2-15/9x+(15/18)^2=-6/9+225/324

(x-15/18)^2=-216+225/324

(x-15/18)^2=9/324

x-15/18=±3/18

x1=18/18=1

X2=12/18=2/3
