Answer:
Step-by-step explanation:
If u = 6 then substitute so
6(6+6)=6 know solve but this isn't going to be correct because 6 plus 6 is 12 times 6 isn't 3
So your answer isn't correct. I think it would be a negative number or decimal because 6 is larger than 3. Hope this helps!
it is u(u+6)=3
I got u=6
g(x) = 3x² + 2x - 1
g(-1) = 3(-1)² + 2(-1) - 1
= 3(1) -2 -1
= 3 - 3
= 0
