Solve by Completing the Square: x2+14x−32=0

since that is y=0 and we are dilating by 1/4 the line is still y=0 because 0 times 1/4 is 0.

same line.

step-by-step explanation:

so you are also going to be dilating the points on that horizontal line by a scale factor of 1/4.   i'm going to identify 3 points on the line that is already given:

(-1,0) , (0,0) , (1,0)

take note this is a horizontal line; all of it's y-coordinates are 0. this line is y=0.

so we are going to multiply each point by 1/4.

these points keep that y-coordinate of 0 since 1/4 times 0 is 0. so this is still the same horizontal line y=0.
