Question

the root of the equation (x+1) (x+2) (x+3) (x+4) = 120 is

Answer 1

Answer:

x= 1

Step-by-step explanation:

120=5!=5.4.3.2.1

=2×3×4×5

=(x+4)(x+3)(x+2)(x+1)

By observation, using x=1 , we will get the product as 120

Hence, x=1 is one root.

Answer 2

Answer:

let x²+5x=m

(m+4) (m+6)=120

m+4=120
