Answer:
7(2a - b)
Step-by-step explanation:
7 * 2a = 14a
7 * -b = -7b
Answer:
r=4
Step-by-step explanation:
By finding the roots of the polynomial, we conclude that the correct graph is the second one.
<h3>
Which is the graph of the polynomial?</h3>
Here we have the polynomial:
To identify it, we need to find the roots, we can rewrite the equation as:
And we can rewrite the last part by using the Bhaskara's formula:
Then the roots are:
x = -2
x = 1
Then we rewrite:
So the roots are at x = 0, x = -2, and x = 1.
The graph with these roots is the second graph (top right).
