(x-1)(x-2)(x+3)(x+4)+4 factorization
Answers
Step-by-step explanation:
(x+1) (x+2)(x+3) (x+4) --15
( x+1)(x+4) = x^2 +5x +4:
(x+2) (x+3) = x^2 +5x+6
Now let us put x^2 + 5x+4 = m
The given problem is in terms of m
m (m+2) --15
m^2 +2m --15
Factoriese
m^2 +5m --3m --15
m (m+5) -3 ( m+5)
(m +5) (m--3)
Now factoriise
m+5 = x^2+5x+4+5 = x^2+5x+9
m-3 = x^2+5x+4 --3 = x^2+5x+1
(x^2+5x+9) (x^2 +5x +1) are the factors
Unless each is expressed as quadratic equation
The given problem should have 4 factors
The rest you can do
4 roots will be the answer

Given:-(x-1)(x-2)(x+3)(x+4)+4 factorization
it is a special case of factorization
to solve the sum we use FOLLOWING steps as below:-
(x-1)(x-2)(x+3)(x+4)+4
=(x-1)(x+3)(x-2)(x+4)+4
=(x²+3x-x-3)(x²+4x-2x-8)+4
=(x²+2x-3)(x²+2x-8)+4
=(a-3)(a-8)+4[let a =x²+2x]
=(a²-8a-3a+24)+4
=a²-11a+24+4
=a²-11a+28
=a²-7a-4a+28
=a(a-7)-4(a-7)
=(a-4)(a-7)
=(x²+2x-4)(x²+2x-7)[putting the value of a]
so the final answer =(x²+2x-4)(x²+2x-7)
here we used common method means we find out here the common terms and in their places we place the a and then we use middle term factorization
