Question

find the roots of 3xsquare+11x+10 by completing square method ​

Answer 1

Step-by-step explanation:

3xsquare+11x+10

x2+11x/3+10

x2+11x+121/36-121/36 +10

(x+11/3)2-(121/36-10)

(x+11/3)2 -(139/36)

(x+11/3)2 -( root139/6)2

(x+11/3-root139/6) (x+11/3+root139/6)

[X + (22 - root 139 )upon 6 ] [X + (22 + root 139) upon 6 ]

[X + (22 - root 139) upon 6] =0

x= -(22-root139)/6

and x= -(22+root139) /6
