The Total solution for NCERT class 6-12
What should be added to the polynomial x2 – 5x + 4, so that 3 is the zero of the resultingpolynomial ?(a) 1(b) 2(c) 4(d) 5
(b)
3 is the zero of the polynomial f(x) = x2 – 5x + 4x – 3 is a factor of f(x)Now f(3) = (3)2 – 5 x 3 + 4 = 9 – 15 + 4 = 13 – 15 = -2-2 is to be subtracting or 2 is added
