1. Sole the equation. Express numbers in exact simplest form.
0 = 49h^2 - 4
2. Use the function g(x) = -x^2 + 3x + 1 to find the indicated function.
g(-5)
Checking if this answer is -39
-(-5)^2 + 3(-5) + 1 = -25 - 15 + 1 = -39
3. 27m^2 - 90mn + 75n^2
I took the GCF of 3 out first
3(9m^2 - 30mn + 25n^2)
I'm not certain of my next steps.
Thank you.
0 = 49h^2 - 4
4 = 49h^2
h^2 = 4/49
h = ± 2/7
g(x) = -x^2 + 3x + 1
f(5) = -39
3(9m^2 - 30mn + 25n^2)
= 3(3m - 5n)^2
