A quadratic equation is an equation whose leading coefficient is of the second degree. The factored form of the quadratic equation x²-x-2 is (x+1)(x-2).
<h3>What is a quadratic equation?</h3>
A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers.
It is written in the form of ax²+bx+c.
The factored form of the quadratic equation can be done in the following manner,
Thus, the factored form of the quadratic equation x²-x-2 is (x+1)(x-2).

Answer:
Domain: 
Range: ![(-\infty, 3]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%203%5D)
Decreases over: 
Step-by-step explanation:
Given
--- Missing from the question
Solving (a): The domain
To get the domain, the expression under the square root must not be negative.
In other words:
Solve for x
Hence, the domain is:
To get the range, we plot the values of the domain in the expression.
So, the range is:
To get the interval where the function increases or not, we simply plot the graph of f(x).
See attachment for graph.
From the attachment, it will be observed that the graph of f(x) continuously decreases from x = -1, and it never increased.
This implies that, the graph decreases over the interval
None of the above..........
Answer:I am pretty sure it is the angels because the square can be a right and the roofs can be acute.
Step-by-step explanation:
Right angle is 90 degrees
Acute is less than 90 degrees
Obtuse is more than 90
Here, slope (m) = y2 - y1/x2-x1
m = 5 - (-3) / 4 - (-2)
m = 8 / 6
m = 4/3
Now, y-y1 = m(x-x1)
y - 5 = 4/3 (x - 4)
y - 5 = 4x/3 - 16/3
y = 4x/3 - 1/3
Hope this helps!
