I find it useful to use a graphing calculator to find the zeros of higher-order polynomials. Once you find one or more rational zeros, you can factor them out to find the reduced polynomial factors (or you can use synthetic division).
1. This factors as (5x+2)(3x-1)(x-8). Roots are {-2/5, 1/3, 8}
2. This factors as (x-9)(x²-5x+2). Roots are {2.5-√4.25, 2.5+√4.25, 9}
3. This factors as (x-6)(5x²+3x+1). Roots are{-0.3-i√0.11, -0.3+i√0.11, 6}

Answer: Absolute value
Step-by-step explanation: Absolute value means <em>distance from zero</em> on a number line. We represent the absolute value of a number by using a vertical bar on either side of the number. Absolute value will always be positive except for 1 special case which I provided in the image attached.
3x-2 = 3x+4x+28x
3x-2 = 7x + 28

Answer:
y -1 = -1(x -2)
Step-by-step explanation:
The slope of the line through the two points can be found from the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (5 -1)/(-2 -2) = 4/-4 = -1
The point-slope equation for a line through point (h, k) with slope m is ...
y -k = m(x -h)
You have (h, k) = (2, 1) and m = -1. Putting these values into the form gives ...
y -1 = -1(x -2)

<em>Additional comment</em>
Your problem statement already has two of the three values filled in, so you only need to enter the x-coordinate of the first point: 2.
