Answer:
use the quadratic formula
Step-by-step explanation:
from the equation a=6 b=-14 c=-9
from the quadratic formula
[tex]x = ( - b {+ or - } \sqrt{ {b}^{2} + 4ac} ) \div 2a[/tex]
therefore insert in the values of a, b and c
[tex]x = ( - ( - 14) + or - \sqrt{ {( - 14)}^{2} + 4 \times 6 \times ( - 9)} ) \div 2 \times 6[/tex]
x=2.858148594
X=-0.52481526
after inserting
