Solve the following quadratic by using square root property. x2 + 16 = 0 A. X= 16 , x= -16

B x = 4, x= -4

C x= 4i , x= -4i

answer: (1,3) and (-2,0) i think.

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
