Solve x2 − 8x + 5 = 0 using the completing-the-square method. (2 points)

Step-by-step explanation:

We use a process called completing the square, which works for all quadratic equations. Here it gives

x=4±√11

Step-by-step explanation:

Hope it is helpful.....

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
