Question

Use the remainder theorem to find the value for each when:

f(x) = x4 + 3x2 + 5
g(x) = x3 -3x2 +x -7

g(3)

Answer 1

@Loser66

Answer 2

put x = 3 in g(x)

Answer 3

g(x) = x3 -3x2 +x -7
g(3) = 3^3 - 3(3)^2 + 3 -7

Answer 4

simplify

Answer 5

yes, rsadhvika is right. to find the remainder, you just plug yhe number into the function and calculate it . that's it

Answer 6

g(3) = 27 - 27 +3-7 =-4

Answer 7

i got that -4

Answer 8

ok that's ok

Answer 9

you don't understand why it is negative, right?

Answer 10
