Question

solve the following quadratic equations by completing the square method
3x square + 2x-1=0​

Answer 1

Answer:

x=rt2/3-1/9    or    x= -rt2/3-1/9

Step-by-step explanation:

3x^2+2x+1=0

x^2+(2x)/3+1/3=0

x^2+(2x)/3=-1/3

x^2+(2x)/3+1/9=-1/3=1/9

(x+1/9)^2=1/9-3/9

(x+1/9)^2=-2/9

(x+1/9)=rt(-2/9)  

x=rt2/3-1/9    or    x= -rt2/3-1/9
