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
2 answers:
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)

Step-by-step explanation:
Convert everything into decimals and add it up
(3/5)b - 7 = a
Remember "of" means to multiply. Less than means subtraction: 7 less than means -7.
Answer:you can't factor a prime number!!! You really should read the book, then you have a chance on the final when you don't have access to Y!A.
