Question

plzz solve this problem ​

Answer 1

let the function = f(x)

f(x) = (x - 3) ( x - 4) g(x) + (ax + b)

using remainder theorem,

f(3) = 0 + (3a + b) = 3a + b = 10 .....(1)

f(4) = 0 + (4a + b) = 4a + b = 15 .....(2)

solving eqn (1) & (2),

(2) - (1)

=> a = 5,

so, b = -5

so,

required remainder = ax + b = 5x - 5 ..... ans...
