Answer:
Step-by-step explanation:
To find the real zeros you must match the function to zero and factor the expression.
We have a polynomial of degree 3.
We try to group the terms to perform the factorization
Now we take (x + 4) as a common factor
If we have an expression of the form we know that this expression is equivalent to:
In this case
So:
Finally:
The solutions are:
Answer:
- (2, 0)
Step-by-step explanation:
<u>Given system:</u>
- x - 2y = 1
- 2x - y = 2
In order to solve it graphically, graph both lines and find the point of their intersection.
Graphing easy if you plot the x- and y- intercepts and connect them with a line.
<em>See attached.</em>
Both lines have same x-intercept, which is also the solution: (2, 0)
