Answer :

(5x + 2)(1 – 5x)(5x + 3)


Here we have to use the identity


(x + a)(x + b)(x + c) = x3 + (a + b + c)x2 + (ab + bc + ca)x + abc


– (5x + 2)(5x – 1)(5x + 3)


here x = 5x, a = 2, b = – 1 and c = 3


= – (5x)3 – (2 – 1 + 3)(5x)2 – (– 2 – 3 + 6)5x + 6


= – 125x3 – 100x2 – 5x + 6


Here coefficient of


x2 = – 100


x = – 5 and


constant term = 6
