The fourth option.
The roots of x^3 + 3x^2 - 5x - 15 are - 3, +√5 and -√5.
To find the roots you can factor the polynomial in this way:
x^3 + 3x^2 - 5x - 15 = x^2 (x + 3) - 5(x + 3) = (x +3)(x^2 - 5)
The roots are the values of x that make the function = 0.
Then the roots are
x + 3 = 0 ==> x = 3, and
x^2 - 5 = 0 ==> x = +/- √5.
0.97222222222
both of the numbers are negative so the answer will be positive. and then you divide the two numbers
Not the greatest example, but the only way I could really show you what the graph looks like. Hope it helps
