Solve the equation by completing the square. round to the nearest hundredth if necessary. 4x2 + 8x – 32 = 0

For this case we must solve the following expression by completing squares:

We divide between 4 on both sides of the equation:

We add 8 to both sides of the equation:

We divide the middle term between 2 and square, this we add to both sides of the equation:

We apply root to both sides:

We have two roots:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

answer: your answer is a
