To find critical points, take the first derivative and set it equal to zero:
f(x) = -2x^2 + 4x + 5
f'(x) = -4x + 4
-4x+4 = 0
-4x = -4
x = 1
Critical point at x = 1
Alternatively, if you mean zeros, or where the x intersects, you can use the quadratic equation.
Answer:
a^3b^4
Step-by-step explanation:
You have 3 a's, so that would be

and you have 4 b's so that would be

so putting it together gives you
