simplify (m-7+sqrt(7))(m-7-sqrt(7))

simplify

(m - 7 + 7) (m - 7 - 7)

m^{2} - 14 m + 42

Solution steps

(m - 7 + 7) (m - 7 - 7)

Distribute parentheses

= mm + m (- 7) + m (- 7) - 7 m - 7 (- 7) - 7 (- 7) + 7 m + 7 (- 7) + 7 (- 7)

Simplify

mm + m (- 7) + m (- 7) - 7 m - 7 (- 7) - 7 (- 7) + 7 m + 7 (- 7) + 7 (- 7) : m^{2} - 14 m + 42

= m^{2} - 14 m + 42
