2sinx+1 equals 0
For y - 2y - 3y equals 0, y equals 0.
many solutions
"x equals 0" is an equality, not an inequality. The question is, therefore, not consistent.
Suppose x3-4x = 0. To solve, factor: x3-4x = x(x2-4) = x(x+2)(x-2) = 0 Now, a product equals 0 if and only one or more of the factors equals 0, so set each factor to 0 and solve. The roots are 0,-2 and +2.

x: x2 - 81 = 0
Solve this problem -x squared -40x- 80 =0
10x=x 9x=0 x=0
Divide both sides by 8: m = 0
x=-.25.
-y + y equals 0.
5 ^x = 0 5 = root square 0 5=0
