Answer:
It is A
Step-by-step explanation:
Divide both sides by -3, and replace
with
. Then

Factorize the quadratic in
to get

which in turn means

But
for all real
, so we can ignore the first solution. This leaves us with

If we allow for any complex solution, then we can continue with the solution we ignored:

No, 4/10 is equal to 0.40 and not 0.45 since 4/10 goes in tens.
let me know if the propositions they gave don't match with mine.
