25 POINTS QUICK TIMED TEST
Half of the product of two consecutive numbers is 105. Which equation can be used to solve for n, the smaller of the two numbers?

n2 + n – 210 = 0
n2 + n – 105 = 0
2n2 + 2n + 210 = 0
2n2 + 2n + 105 = 0

Answer 1

Step-by-step explanation:

n²+n-210

n(n+1)=210

Consecutive number : n and (n+1)'s Product is 210

and Half of there Product would be 105,Obviously.

Answer 2

Answer:

n2+n-210 is the answer
