When simplifying you want to combine like terms so 14x²-12x² will equal 2x², now we move on to X, where 3x+11x will result in 14x, last we add up numbers without X so 4-3 is 1.
The Answer will end up being 2x²+14x+1 (B)
I assume you mean 
, and not 
, since this doesn't satisfy the ODE.
Assume a second solution of the form 
, where 
is a function of 
. Then
Substituting into the ODE gives
where we omit the second term because it's already accounted for by 
.
I believe the answer is 375
Answer:
C. 5 × 3
Step-by-step explanation:
The order of a matrix is the number of rows and columns that a matrix has. Rows are listed first and columns are listed second. The matrix has 5 rows going across horizontally and 3 columns going down vertically.
So, the order of the matrix is 5 × 3.
Hope that helps.
