Should be D. 2x65=130-20=110
Answer:
1
Step-by-step explanation:
The quadratic function
y = -2(x + 2)² - 1
has no real zeros because its vertex is located at (-2, -1) and it opens downward (the leading coefficient, -2, is negative)
A quadratic function has one real root if its vertex has the form (x, 0). If we add 1 to our equation, we get:
y = -2(x + 2)² - 1 + 1 = -2(x + 2)²
which has point (-2, 0) as vertex
Answer:
14
Step-by-step explanation:
Option A, The option that has the same potential roots according to the rational root theorem is 3x5 – 2x4 – 9x3 + x2 – 12.
<h3>How to solve for the roots</h3>
We have p, this is the factors of the number 12.
The factors are ±(1, 2, 3, 4, 6, 12)
We have factors of q = 3
= ±(1, 3)
The rational roots are the roots that have the same factors that are contained in the question.
Hence the answer is A.
