Question

solve 6x^2 - x -2 = 0 by completing square method

Answer 1

Step-by-step explanation:

(6x²-x-2=0)/6

x²-x/6-1/3=0

a=1 b=1/6*1/2=1/12

{x²-2(1)(1/12)x+(-1/12)²}-(-1/2)²-1/3=0

a²+2ab+b²=(a+b)²

(x-1/12)²-1/144-1/3=0

(x-1/12)²=1/144+1/3

x-1/12=√147/432

x-1/12=+/-7√3/12√3*√3/√3=21/36

x=+21/36+1/12=24/36=2/3

x-21/36+1/12=18/36=-1/2.

This is also 1method.
