Answer:
(2,-4)
Step-by-step explanation:
-4+2=-2
10+-4=10-4=6
0.739 is the answer that I got (this is not a rounded answer by the way)
hope it helps :)
Y-intercept: (0, -6)
x-intercept: (-8, 0)
No because it would be
if you knew that
ax^2+bx+c was a trinomial square, then the factored form would be

or

so
if w^2-9w+81 is perfect square, factored form is either

or

aka

or
expand them
(x+9)^2=x^2+18x+81, wron middle term
(x-9)^2=x^2-18x+81 wrong
so it is not
2/5 more i believe!
basically just subtract 4/5 and 2/5 and you get 2/5
feel free to mark brainliest, hope this helps!
