Question

plz help fast.... options are provided...What number added to the polynomial $3x^{2} +5x$ gives the square of a first degree polynomial?
(a)25/12
(b)25/24
(c)25/36
(d)25/48

Answer 1

(a)25/12 is right. therefore The remainder is (3x + 1) Hence [ – (3x + 1)] should be added to 3x4+ 5x3 – 7x2 + 5x + 3 so that the resulting polynomial is exactly divisible by (x2+3x+1).
