Question

What number added to 3x3 + 2x2 + 5x gives a polynomial for which x-1 is a factor?

Answer 1

Answer:

hi bro.... if we want a number which must be added to make x-1 factor would be the remainder.

Step-by-step explanation:

so..

let x-1 be g(x)

and f(x) be

$3 {x}^{3} + {2x}^{2} + 5x$

on dividing fx with gx

we get...

$\frac{ {3x}^{2} + {2x}^{2} + 5x}{x - 1}$

here.... we got remainder as ..0

hence 0 must be added to polynomial.

hope it helps....
