maths question by reminder theoram​

Answer 1

Answer:

16

Step-by-step explanation:

Let f(x) = 12x^3 +23x^2 - 4x - 15

x-1 = 0

x = 1

The remainder theorem states that if f(x) is divided by (x-1) then the remainder is g(1).

The remainder is

f(1) = 12(1)^3 + 23(1)^2 - 4(1) - 15

= 12 + 23 - 4 - 15

= 35 - 19

= 16

The remainder will be 16.
