If you would like to solve the system of equations x + y = 3 and 2x - y = 6, you can do this using the following steps:
<span>x + y = 3 ... y = 3 - x
2x - y = 6
</span>_________
<span>2x - y = 6
</span>2x - (3 - x) = 6
2x - 3 + x = 6
3x = 6 + 3
3x = 9 /3
x = 9/3
x = 3
<span>y = 3 - x = 3 - 3 = 0
</span>
The correct result would be x = 3.
Answer:
Solving the equation
using quadratic formula we get 
Step-by-step explanation:
We need to solve the equation
using quadratic formula.
The quadratic formula is:

where a=1, b=-8 and c=41
Putting values in formula and finding x

So, Solving the equation
using quadratic formula we get 
To solve this problem you must apply the proccedure shown below:
1. You have the following functions given in the problem above:

and

<span>
2. You have that g(x) times f(x) can be written as g(x)*f(x). Therefore, you must multiply f(x) * g(x), as following:
