X2 - 4x + 4 a. 4(x2 - x + 1) b. (x - 2)(x + 2) c. (x + 2)(x + 2) d. (x - 2)(x - 2)

  D.  (x - 2)(x - 2)

Step-by-step explanation:

x² - 4x + 4 = (x -2)(x -2)

___

The expression matches the form ...

  (a +b)² + a² +2ab +b²

where a = x and b = -2

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
