`x(x+1)(x+2)(x+3)=120 : x=`

Find number of integer roots of equation x(x+1)(x+2)(x+3)=120

Solve :(x+1)(x+2)(x+3)(x+4)=120

Solve the equations: (x+1)(x+2)(x+3)(x+4)=120

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

(x^(2)+5x+1)/((x+1)(x+2)(x+3))=(A)/(x+1)+(B)/((x+1)(x+2))+(C)/((x+1)(x+2)(x+3)) then B=

If f(x)=det[[x-2,(x-1)^(2),x^(3)(x-1),x^(2),(x+1)^(3)x,(x+1)^(2),(x+2)^(3) then coefficient of x in f(x), is ]]

If D(x)=det[[(x-1),(x-1)^(2),x^(3)(x-1),x^(2),(x+1)^(3)x,(x+1)^(2),(x+1)^(3) then the coefficient of x in D(x), is ]]

Check whether the following are quadratic equations : (1) (x-1)^(2)=2(x-3) (2) x^(2)-2x=(-2)(3-x) (3) (x-2)(x+1)=(x-1)(x+3) (4) (x-3)(2x+1)=x(x+5) (5) (2x-1)(x-3)=(x+5)(x-1) (6) x^(2)+3x+1=(x-2)^(2) (7) (x+2)^(3)=2x(x^(2)-1) (8) x^(3)-4x^(2)-x+1=(x-2)^(3)
