I am trying to create real life situation word problem that fits into the equation (x + 3)(x - 4) = 0, and also express the situation as the same equation.

I am a number. When I am subtracted by my square, I get 12. What number am I?
Solution:
let x = the number. Then, the number's square is x^2, so
x^2 - x = 12
x^2 - x - 12 = 0
(x-4)(x+3) = 0
x = 4 or x = -3
Therefore, the number I am is 4 or -3.

3x-4(x+a million)+10=0 first u distribute the 4 into the volume interior 3x-4x-4+10=0 then combine like words -x+6=0 then subtract 6 from both area -x=-6 then divide with the aid of -a million to make x effective x=6

I can think of only a mathematical question: What two points on a XY graph will show X to be 0?
They are when X=-3 and X=+4

Michael has some smarties. He puts them in a line on the playground wall. His friend Gillian adds more lines of smarties of the same length underneath Michael's line, so as to make a square. Michael takes away his smarties. 12 smarties are left. How many smarties did Michael have?
