If it's not what You are looking for type in the equation solver your own equation and let us solve it.
-(x+2)(x-5)(x-3)(x+3)=0
We multiply parentheses ..
-(+x^2-5x+2x-10)(x-3)(x+3)=0
We use the square of the difference formula
x^2+9=0
a = 1; b = 0; c = +9;
Δ = b2-4ac
Δ = 02-4·1·9
Δ = -36
Delta is less than zero, so there is no solution for the equation
