Question

find the remainder when x^3+3X^2-7x+2 is divided by x+1

Answer 1

Answer:

i. Between the first and second vertebrae_____

Answer 2

Answer:

Step-by-step explanation:

x3 - 3x2 + 7x - 5

Simplify —————————————————

x - 1

Checking for a perfect cube :

2.1 x3 - 3x2 + 7x - 5 is not a perfect cube

Trying to factor by pulling out :

2.2 Factoring: x3 - 3x2 + 7x - 5

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

Group 1: 7x - 5

Group 2: x3 - 3x2

Pull out from each group separately :

Group 1: (7x - 5) • (1)

Group 2: (x - 3) • (x2)

The groups have no common factor and can not be added up to form a multiplication.
