discriminant= b^2-4ac= (-2)^2-4(4)(9)= -140<0
since discriminant <0, graph is always positive, x has no real roots
Answer:
- c = 9
Step-by-step explanation:
given c = - 9 ← multiply both sides by - 1
c × - 1 = - 9 × - 1 ⇒ - c = 9
Solution:
As we given that
then using this conversion factor we can write 
and further it can be written as

Hence the required conversion factor is 2.54 cm/1 inch as we can see from the above calculation.
