Answer:

(m + 5)(m + 2)

Step-by-step explanation:

a² - b² = (a - b)(a + b)

(a ± b)² = a² ± 2ab + b²

~~~~~~~~

m² + 7m + 10 =

(m² + 2 × \frac{7}{2} × m + \frac{49}{4} ) - \frac{49}{4} + 10 =

(m + \frac{7}{2} )² - (\frac{3}{2})² = (m + \frac{7}{2} + \frac{3}{2} )(m + \frac{7}{2} - \frac{3}{2} ) =

(m + 5)(m + 2)
