Can you please walk me through how to best approach this problem? Thanks
If #p# = ap^3+ bp – 1 where a and b are constants, and #-5# = 10, what is the value of #5#?  Choose the correct choice from the following answers:  A) 5  B) -12  C) -2  D) -3  E) -5
#p# = ap^3 + bp - 1   #-5# = 10   putting p = -5 in above equation   -125a -(5b +1) = 10 or   #-5# = (125a+5b+1) = -10   therefore 125a+5b = -11 .....(1   now putting p = 5   #5# = 125 a+5b - 1   using equation 1(125a+5b = -11)   #5# = -11-1 = -12   hence -12
<result>B</result>
