Find the value of the discrimination and the number of real-number solutions in the below equation:
x^2+7x+8=0
can you explain how to do this step-by-step? i have more questions similar to this one that i need to be able to answer.
in advanced : )

i’m sorry but i don’t know sorry

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
