Answer:
or
Step-by-step explanation:
We use casework on when and when
.
For the first case, , we add 9 to both sides to get
.
Dividing both sides by 3 gives
For the second case, , we add 9 to both sides to get
.
Dividing both sides by 3 gives
.
Checking both cases, we plug in and
.
For the first case, we have , which satisfies the equation.
For the second case, we have , which also satisfies the equation.
This gives us two solutions to the equation; and
.
Answer:
x = -4
x = -1
Step-by-step explanation:
We have been given the following quadratic equation;
x^2 + 5x + 4 = 0
We are required to determine the roots of the above quadratic equation via graphing.
To do this we formulate the following equations;
y = x^2 + 5x + 4
y = 0 (x -axis)
We then proceed to graph these functions on the same graph. The roots of the original quadratic equation will be the points where the graphs of the above functions will intersect.
The attachment below is the graphical solution obtained from desmos graphing tool;
The graph of the functions intersect at;
x = -4 and x = -1
These are the roots of the given quadratic equation
