Solve 2x2 + 8x - 12 = 0 by completing the square. What are the solutions? {2 -10 , 2 -10 } {-2 + 6, -2 -6 } {-2 +10 , -2 -10 }

what is all that apply?

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;
