Question

In each pair of polynomials given below, find the number to be sub-
tracted from the first to get a polynomial for which the second is a factor.
Find also the second factor of the polynomial got on subtracting the
number
(1) -3x+ 5 - 4
(ii) x - 3x + 5, x + 4
(ii) + 5x - 7, x-1
(iv) x² - 4x -3x - 1​

Answer 1

Answer:

$- 3 \times + 5 - 4$

Answer 2

Answer:

ii) x square-3x+5,x+4

P(x)=x square-3x+5,x+4

P(-4)=-4square-3x×-4+5

=16+12+5=28+5=33.

=xsqure-3x+5-33

=xsqure-3x-28=0

answer =

=factors=(x-7)×(x+4)
