X^2 -5x -20=0
(x - 5/2)^2 -20 -25/4=0
(x-5/2)^2-105/4=0
(x -5/2 -(105)^1/2)(x -5/2 +(105)^1/2)=0
factors are (x -5/2 -(105)^1/2) and
(x -5/2 -(105)^1/2)
Hello!
Here we are given a second-order polynomial, and the root form of the function.
Where c and d are zeros of the function, which is where the graph intersects the x-axis.
Therefore, the equation of this polynomial would be , and the values of a and b would be the x-intercepts.
Hope this helps!
Answer:i simplified it and got 9 so 3 to the second power
Step-by-step explanation:
Answer:
20.8
Step-by-step explanation:
Answer:
y = -2x - 1
Step-by-step explanation:
X : Y
-2 : 3
<u>0 : -1</u>
1 : -3
3 : -7
First we have to find the y intercept we do that by looking at the table and finding what y = when x = 0
Then to find the slope we do the change in y over the change in x so when y changes by what what does x change by in this question it's when y goes down to or -2 x goes up one -2/1x = -2x
