What is the value of n in the expression x cubed plus nx squared plus 3x -5 when divided by x -2 with a remainder of -3 showing brief details of your work?
Use the remainder theorem:- f(x) = x3+nx2+3x-5 f(x) becomes f(2) because the divisor is x-2 and 2-2 = 0 f(2) = 8+4n+6-5 = -3 f(2) = 4n+9 = -3 f(2) = 4n = -12 f(2) = n = -3 So the value of n in the expression is -3 Check: f(2) = 8+(4*-3)+6-5 = -3
