Answer:
- ac = -16
- b = 0
- -4, 4
- (4x -1)(4x +1)
Step-by-step explanation:
a) ac is the product of the leading coefficient (16) and the constant (-1).
ac = (16)(-1) = -16
__
b) b is the coefficient of x. There is no x term, so ...
b = 0
__
c) Two factors that add to give zero must be opposites. That is, they must be the square root of the opposite of -16, and the opposite of that.
the two numbers are -4 and 4
__
d) The factored form for the two numbers p and q just found is ...
ax^2 +bx +c = (ax +p)(ax +q)/a
= (16x -4)(16x +4)/16
= (4x -1)(4x +1) . . . . factored form of 16x^2 -1

Answer:
The answer is D because the angles ABC are not corresponding to DEF
Answer:
Option 1 is a geometric sequence.
I 1/4, 1/4, 1/4, 1/4
II 1/4, 1/5, 1/6
III 1/4, 1, -4, 1/6
IV 1/4, -4, 1/4, -4
For any geometric sequence there should be a common ratio
To find common ratio we divide consecutive terms
lets check option I
I 1/4, 1/4, 1/4, 1/4
When we divide 1/4 by 1/4 we will get 1
Same 1 for other two terms, so common ratio is 1
Hence the first option is a geometric sequence
