Solving the equation
(x+5)(x+4) = 0
According to the zero product rule....
either x+5 = 0 => x = -5
or x+4 = 0 => x = -4
so x = -4 or -5
Solving 2nd equation
2h^2-h-3 = 0
2h^2 - 3h + 2h -3 = 0
=> h(2h-3) + (2h-3) = 0
=> (2h-3)(h+1) = 0
=> according to zero product rule
either 2h-3 =0 => h = 3/2
or h+1 = 0 => h = -1
so h = -1 or 3/2
