Q:
# Which equation is y = (x + 3)2 + (x + 4)2 rewritten in vertex form? mc010-1.jpg mc010-2.jpg y = 2(x + 7)2 – 73 y = (x + 7)2 – 24

Accepted Solution

A:

y=(x+3)²+(x+4)²

y=x²+6x+9+x²+8x+16

y=2x²+14x+25

y=2(x²+7x+3.5²-3.5²)+25

y=2(x+3.5)²-2*3.5² +25

y=2(x+3.5)²+0.5

y=x²+6x+9+x²+8x+16

y=2x²+14x+25

y=2(x²+7x+3.5²-3.5²)+25

y=2(x+3.5)²-2*3.5² +25

y=2(x+3.5)²+0.5
