Factor 125-64m^3 completely. Answer Attemption of disappointed

To factor the expression $125 - 64m^3$ completely, we can use the formula for the difference of cubes. The difference of cubes formula is given by:<br /><br />$a^3 - b^3 = (a - b)(a^2 + ab + b^2)$<br /><br />In this case, we can rewrite $125 - 64m^3$ as $(5 - 4m)(25 + 20m + 16m^2)$.<br /><br />Therefore, the completely factored form of $125 - 64m^3$ is $(5 - 4m)(25 + 20m + 16m^2)$.
