Question

8th grade 50 POINTS+BRAINLIEST: How do you graph a quadratic equation in vertex form when the equation is a perfect square? Use x² -4x+4 as an example

Answer 1

Answer:

(x - 2)² + 0

Step-by-step explanation:

Using x² - 4x + 4

(x² - 4x + 4)

x² - 4x + (-2)² - (-2)² + 4 (complete the square)

(x - 2)² - ( -2)² + 4 (use the binomial formula)

(x - 2)² + 0

Vertex point at (2,0)

Answer 2

Answer:

(x - 2)² + 0

Step-by-step explanation:
