Question

1) if (x-2) is a factor of x^2-ax+4, then the value of 'a' is a) 4 b) 2 c) -4 d) -2 2) if f (x) =3x-2, then the value of f (2) is a) 4 b) 3 c) 1 d) 0 3) a cubic polynomial can have at most a) one zero b) two zeroes c) three zeroes d) four zeroes 4) if 16x^4-8x^3+x^2-8x+4 is divided by (2x-1), then the remainder is a) 2 b) 1/4 c) 3/2 d) 4 5) if f (x) = x^4-4hx^2+27x-12h and 'x' is a factor of f (x) , then h = a) -12 b) 0 c) 6 d) 5​

Answer 1

(2) . sub f(x) =2

        3(2) -2= 6 -2 = 4

                therefore , option a) 4 is correct answer .

(3) . a cubic polynomial can have 3 zeroes

(4). 17/4 is answer
