Question

PLS HELPPPP
Solve 3x2 + 18x + 15 = 0 by completing the square.
I CANT FIND REAL ANSWER!

Answer 1

1.2

Explanation:

3x2+18x+15=0

6+18x+15=0

6+18x-15=0-15

6+18x=-15

-6+18x=-15+(-6)

18x=-21

18/18x=21/18

x=1.2

( i might have messed up somewhere if so sorry )

Answer 2

x = − 1 , − 5
