By completing squares, we will see that the solution set of the quadratic equation is {-12, 2}.
<h3>
How to complete the square?</h3>
Remember the relation:
Here we start with:
Then, we can rewrite it to get:
Now we can see that a = x and b = 5, then we can add and subtract 5 squared in the left side, so we get:
Now we can solve our equation:
So the solution set is {-12, 2}

-4
The elephant lost 4 pounds each month. Because he is losing weight, and not gaining weight, you have to make the answer negative.
Answer:
C y = 1/3 x - 1
Step-by-step explanation:
The y-intercept is -1, so b = -1.
The slope is run/rise = 1/3
Equation:
y = 1/3 x - 1
This product involves zero. So, you don't have to bother and compute all the factor, because if you multiply anything by zero you get zero.
