Which product of prime polynomials is equivalent to 8x4 + 36x3 - 72x2?
4x(2x - 3)(x2 + 6)
4x²(2x - 3)(x + 6)
2x(2x - 3)(2x2 + 6)
2x(2x + 3)(x2 – 6)

answer: group b.

step-by-step explanation:

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;

once you solve it out the value of x is 13
