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
I hope this is helpful!

Answer:
x=6 and y=2
Step-by-step explanation:
3x-2y=14 _1st equation
5x+y=32 _2nd equation
Multiplying 2nd equation by two and adding both equation
3x-2y=14
10x+2y=64
_________
13x=78
x=78÷13
x=6
Putting the value of x in 1st equation
3×6-2y=14
18-2y=14
2y=18-14
2y=4
y=4÷2
y=2
