Q . A polynomial in x of degree greater than 3 leaves remainder 2, 6, 12 when divided by x, (x— I) and (x-2) respectively. If R(x) be the remainder when polynomial is divided by x(x - l) (x- 2), then (A) R(x) is a quadratic polynomial (B) R (x) have real roots (C) R (x) integer roots (D) R (10) = 132 Share with your friends Share 6 Neha Sethi answered this Dear student Given that:f0=2f1=6f2=12Let fx=pxxx-1x-2+ax2+bx+c Now putting f0=c⇒2=c ...(1)f1=a+b+c⇒6=a+b+c6=a+b+2 [using 1]a+b=4 a=4-b ...(2)f2=4a+2b+c12=4a+2b+c12=4(4-b)+2b+2 [using 1 and 2]12=16-4b+2b+26=2bb=3and from (2), we geta=4-3a=1 Hence , Rx=x2+3x+2 which is a quadratic polynomial Regards -1 View Full Answer
