Yoo i need help!!
Which are solutions of the equation x2 – 16 = 0? Check all that apply.
x = –8
x = –4
x = –2
x = 2
x = 4
x = 8

1) Use the commutative property to reorder the terms
Which will give you 2x-16=0
2) Move the constant to the right hand side and change the sign
Which will then give you 2x=16
3) divide by both sides
Your answer should be x=8

The vertex of the quadratic function is (1.5, -.75)
