The Total solution for NCERT class 6-12
What should be subtracted to the polynomial x2 – 16x + 30, so that 15 is the zero of the resultingpolynomial ?(a) 30(b) 14(b) 15(d) 16
(c)
15 is the zero of polynomial f(x) = x2 – 16x + 30Then f(15) = 0f(15) = (15)2 – 16 x 15 + 30 = 225 – 240 + 30 = 255 – 240 = 1515 is to be subtracted
