The vertex form: y = a(x - h)² + k
y = x² - 6x + 7 = x² - 2x · 3 + 3² - 3² + 7 = (x - 3)² - 9 + 7 = (x - 3)² - 2
Answer: y = (x - 3)² - 2
Used: (a - b)² = a² - 2ab + b²
For the 2nd picture, c. 26/7
Answer:
Step-by-step explanation:
We have been given an equivalence equation . We are asked to find all the square root of the given equivalence equation.
Upon converting our given equivalence equation into an equation, we will get:
Add 53 on both sides:
Take square root of both sides:
Therefore, the square root for our given equation would be .
