Question

6x²-x-2=0 by completing square method

Answer 1

Answer:

Step-by-step explanation:

6x²-x-2=0

6x²-x=2

multiply by 4*6=24

24*6x²-24x=48

adding (-1)2=1 in both sides

144x²-24x+1=49

(12x)²-2*12x*x+1²=49

(12x-1)²=7²

12x-1=±7

12x=1±7

x=(1±7)/12

so x =1+7/12 or 1-7/12

x=8/12 or -6/12

or x=3/4,-1/2
