<span>f(x) = −7x^4 − 12x^3 + 9x^2 − 17x + 3 you will have to change the signs so,
f(−x) = −7x^4 + 12x^3 + 9x^2 + 17x + 3
For positive roots, count number of times coefficients of f(x) change sign:
− − + − +
3 times -----> 3 or 1 positive roots
For negative roots, count number of times coefficients of f(−x) change sign:
− + + + +
1 time -----> 1 negative root
Positive real: 3 or 1
Negative real: 1
Complex non-real: 0 or 2
The answer is C

Answer:
I am assuming it wants you to put it into digits rather than the words. If so, the answer would be 9 - (g - f)
X equals 18. This might not be correct
Answer:
just remove the bracket and write normally so it's 23x+4-5b
Step-by-step explanation:
if you meant something else then let me know
The answer should be (x-4)^2+(y+2)^2=radical 26
