Question

Using remainder theorem, find the remainder wjen f(x) is divided by g(x) & verify the result by actual division=> f(x) =x^3 +4x^2 -3x+10, g(x) = x+4​

Answer 1

Answer:

reminder is 22

Step-by-step explanation:

f(x) = x³ + 4x² - 3x + 10

g(x) = x + 4

x + 4 = 0

x = -4

put x in f(x)

f(x) = x³ + 4x² - 3x + 10

f(-4) = (-4)³ + 4(4)² - 3(-4) + 10

= -64 + 4(16) + 12 + 10

= -64 + 64 + 12 + 10

= 22
