Ametal cube of edge 12 cm is melted and formed into three smaller cubes. if the edges of two smaller cubes are 6 cm and 8 cm, find the edge of the third smaller cube?

Talia grouped the terms and factored out the gcf of the groups of the polynomial 15x2 – 3x – 20x + 4. her work is shown below. (15x2 – 3x) + (–20x + 4) 3x(5x – 1) + 4(–5x + 1) talia noticed that she does not have a common factor. what should she do?
