Question

Find the remainder, when (x³-7x+2) is divided by (x+2)? ​

Answer 1

Answer:

8

Step-by-step explanation:

Using remainder theorem,

p(x) = x³-7x+2

g(x) = x + 2

To find the remainder when p(x) is divided by g(x)

We find the zero of g(x)

= x + 2 = 0

x = -2

p(-2) = (-2)³ -7(-2) + 2

= -8 + 14 + 2

= 8
