Question

Factorize the following:
16m − 4m²

Answer 1

\[\text{ The greatest common factor of the terms }16m \text{ and }4 m^2\text{ of the expression }16m - 4 m^2\text{ is }4m . \]
\[\text{ Also, we can write }16m = 4m \times 4\text{ and }4 m^2 = 4m \times m . \]
\[ \therefore 16m - 4 m^2 = 4m \times 4 - 4m \times m\]
\[ = 4m(4 - m)\]
