Question

factorise x(x+1)(x+2)(x+3)-24.
Please explain step by step​

Answer 1

Answer:

x (x + 1) (x + 2) (x + 3) -24

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

so, x =2 is the interior root

also, x (x + 1) (x + 2) (x + 3) = (-2) x (-3) x (-4)

here, now x = (-4) is the interior root

since the hight power of the variable x in the expression is 3, the equation must have 3 roots.

however, there are only two integer roots as shown in the equation.
