Answer:
The values of x are:
Step-by-step explanation:
Given the expression
Expand (x - 2)² = x² -4x + 4
Expand: -6(x - 2) = -6x + 12
simplifying
Factor x² -10x + 21: (x - 3) (x - 7)
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
solving x - 3 = 0
x - 3 = 0
Adding 3 to both sides
simplify
x = 3
solving x - 7 = 0
x - 7 = 0
Adding 7 to both sides
Simplify
x = 7
Therefore, the values of x are:
I agree with the statement

y=-2x+1
So, -2x, you go down 2 every time you go across 1. So, the rise is -2, and the run is 1, so it's -2x
+1: when you reach an x of 0, you are still up 1. So, the y-intercept is 1
