Answer:
r-100
Step-by-step explanation:
R-100 R-100 R-100
Answer and Step-by-step explanation:
The signs didn't really "swap". Instead, the whole function was divided by -1, or we could say the function was divided by -3. That would turn:
-18x² - 15x + 3 = 0
into
(-18 / -3)x² - (15 / -3)x + (3 / -3) = 0
6x² + 5x - 1 = 0
And that gives the "swapped signs".
Approximate the real zeros of f(x) = x2 + 3x + 1 to the nearest tenth
