Answer 1

resend the pic it's not clear how to tell

Answer 2

Explanation:

n² -4n+ 4

Sum = -4

Product = 4

Factors : -2 , -2

n² - 4n +4 = n² - 2n - 2n + (-2)*(-2)

= n(n - 2) - 2(n - 2)

= (n - 2) (n - 2) = (n - 2)²

n² - 7n + 10

Sum = -7

Product = 10

Factors: -5 , -2

n² - 7n + 10 = n² - 5n - 2n + (-5)*(-2)

= n(n-5) - 2(n -5)

= (n - 5)(n-2)

n² - 4n +4 = (n-2)²

n² - 7n + 10 = (n - 5)( n-2)

Least common denominator = (n -2)² (n-5)
