0 + 11 = 7 maddox says that the problem cannot be solved because the expression on the left side of the equal sign is undefined. is maddox correct? explain why or why not given what you know about dividing integers.

hFind the least number which leaves a remainder 7 when it's divided by any one of the number : 20, 30 and 40 .

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
