Question

The remainder when x³- 4x²+12x+7 is divided by x +1/2
​

Answer 1

Answer :

f(x)=x^3 - 4x^2 +12x + 7

f(-1/2)=  (-1/2)^3 -4(-1/2)^2 + 12(-1/2) + 7 (according to remainder theorem the f(-1/2) will be the remainder)

            = -1/8 - 4(1/4)  -12/2 +7

            = -1/8 -1 -6 +7

            = -1/8 -7 + 7

            = -1/8 is ur remainder
