Step-by-step explanation:
The answer is the third option, which is:
<span> y = x^2 + 5x + 3
6x + y = −27
The explanation is shown below:
1. When you solve this problem you have the following solution:
x=-6
y=9
x=-5
y=3
2. As you can see the solution corresponds with the graph shown above.
3. You can give value to the variable x of the first equation and values to the x of the second equation, and plot each point obtain. You will see that the parabola and the line, touch each other at the points (-5,3) and (-6,9)</span>
Answer:
Step-by-step explanation:
You have what is called "perfect squares" so you can use the "difference of squares formula to factor:
So,
you can work the equation backward now and you will get your original equation.
