What are the two roots of the equation (4x-8)(x-3) = 0?

Since there are two terms multiplying together, when either of them are equal to zero, the total multiplication will also be zero. Ie, 10 x 0 = 0. This means that to find the two roots, we can simply equate each of the two multiplying terms to zero.4x - 8 = 0, and x - 3 = 0. Rearranging, we get x = 2, and x = 3. Therefore our two solutions are x = 2 and x = 3.
