I would think that it is B. because it makes the most sense to me. it also could be B. for one other reason and that is converting helps to understand how to salve it on pencil and paper if you know how to convert on paper
so my answer would be B.
Answer:
B
Step-by-step explanation:
Step-by-step explanation:
1. y=(x-2)²-9
Using Formula (a-b)²=a²-2ab=b²
y=(x²-4x+4)-9
y=x²-4x-5
Using Mid term Break
y=x²-5x+x-5
y=x(x-5)+1 (x-5)
y=(x+1)(x-5)
2. y= -(x-5)²+16
Using the same formula as above
y= -(x²-10x+25)+16
y= -x²+10x-25+16
y= -x²+10x -9
Taking (-) as Common
y= -(x²-10x+9)
y= -(x²-9x-x+9)
y= -[x(x-9)-1(x-9)]
y= -(x-1)(x-9)
