Does any one know how to solve this -4n^2-2n=-6-7n-5n^2
2 answers:

Answer: n=-2, n=-3
-4n^2-2n=-6-7n-5n^2
Add 5n^2 to both sides
n^2-2n=-6-7n
Add 7n to both sides
n^2+5n=-6
Add 6 to both sides to put the equation into quadratic standard form
n^2+5n+6=0
Factor the equation
(n+2)(n+3)=0
3+2=5, 3*2=6
To solve a quadratic equation, find roots using Zero Product Property.
(n+2)=0
n=-2
(n+3)=0
n=-3
Final answers: n=-3, n=-2
