Im not sure if you wrote this wrong because (x+y)2 does equal x2+y2. An example would be if x equals 3 and y equals 4 (3+4)2=(3)2+(4)2 (7)2=6+8 14=14.
What do you need help clarifying? Did you want to go over the questions you missed? (:
The correct answer are 1 , 3 , 4
The vertex of <span>y = 7x2 + 14x + 4</span> is at
(-1,-3) (see attachment)
Addition: negative four plus negative four plus negative four equals negative twelve
Multiplication: negative four times three equals negative twelve
Division: twelve divided by 3 equals negative four
