To find the answer, you need to determine what the difference is. In this case, the difference is 6.
134 - 128 = 6
140 - 134 = 6
146 - 140 = 6
152 - 146 = 6
So, to find the answer you would add 6 to the next set of numbers to continue the pattern. For example -
152 + 6 = 158
158 + 6 = 164
<h2>Steps:</h2>
So firstly, since we know that the coefficient of x² is 1, this means that this is our base equation:
y = x² + bx + c
Now, since we know that the roots are -7 and 1, set y = 0 and set x = -7 and 1 and simplify:

Now with this, we can set up a system of equations to solve for b and c. For this, I will be using the elimination method. For this, subtract the 2 equations:

Now that the c variable has been eliminated we can solve for b. For this, divide both sides by -8 and your first part of your answer is b = 6.
Now that we know the value of b, plug it into either equation to solve for c:

<h2>Answer:</h2>
<u>Putting it together, your final answer is x² + 6x - 7 = 0.</u>
Answer:
i may not be correct idk but i think its a because it would have to be in between 2.5 and 4.3
Step-by-step explanation:
8 x 9 = 72
So 72 is your answer
