Question

3. 8 (p - 3)3 + 343
​

Answer 1

Step-by-step explanation:

Factoring: 8p3+72p2+216p-127

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: 8p3-127

Group 2: 72p2+216p

Pull out from each group separately :

Group 1: (8p3-127) • (1)

Group 2: (p+3) • (72p)

Bad news !! Factoring by pulling out fails :

The groups have no common factor and can not be added up to

Answer 2

Step-by-step explanation:

=24p-72+343

=24p+271

24p=-271

p=-11.29
