Identify a, b, and c in the quadratic equation. 4x^2-9=0
A. a=4, b=1, c= -9
B. a=4, b=0, c=-9
C. a=4, b=1, c=9
D. a=4, b=0, c=9

y=1/4x-4

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.
