The fact that the coefficients are pairwise identical (except for sign) tells you that x^2 -1 is a factor (and x-5 is the other factor). Of course, you recognize x^2-1 as a special form (the difference of squares) that is factored as (x +1)(x -1).
The zeros are x = -1, +1, +5.
___
A graphing calculator confirms this.
Answer:
Slope: 1; Y-int: (0,2)
Step-by-step explanation:
The slope is rise over run, the equation is y two minus y one divided by x two minus x one.
(3-2) / (1-0) = 1
The y-int. is where the line crosses the y-axis, or the x value is 0.
Hope this helps :)
Answer:
x^2 + 16x + 60 = 0
Step-by-step explanation:
Add 16x to both sides of the given equation. We get x^2 + 16x + 60 = 0.
