Разложите многочлен ** множители: 49-(m-3)²

Question

Разложите многочлен на множители:
49-(m-3)²

Answer 1

49-(m-2)^2=

=(7-(m-3))*(7+m-3)=

=(7-m+3)*(4+m)=

=(10-m)*(4+m)

Answer 2

Формула: a²-b²=(a-b)(a+b)

49-(m-3)²=(7+(m-3))(7-(m-3))=(7+m-3)(7-m+3)=(m+4)(10-m)

Comments

49-(m-3)²=(7+(m-3))(7-(m-3))=(7+m-3)(7-m+3)=(m+4)(10-m)
