Oh, dude, so, like, when you multiply 8 by 0, you get 0, not 4n. It's like trying to make a sandwich with just bread - you're missing the filling! Maybe check your math or see if there's more to the equation that got lost along the way.

100t -16t2 = 0 t4(25-4t) = 0 t = 0 or t = 25/4
Unfortunately you cannot solve this problem since the domain of x (b2-4ac) = 4-4*2*1 = -4Since the root of a negative number does not exist, this problem is nog solvable without the use of imaginary numbers.
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.
(3x+4)(3x-4)=0 x=±4/3
Subtract x so -4 = 2x/ x= -2
