The product of two consecutive natural numbers is greater than their sum by 155. Find these numbers
The product of two consecutive natural numbers is greater than their sum by 155. Find these numbers
(X) • (X+1) = (X) + (X+1) + 155
X2 + X = 2X + 156
X2 – X – 156 = 0
(X+12)(X –13) = 0
X = –12 discard, neg nums aren't natural
X = 13 —> X+1 = 14
check answer
13 x 14 = 182
13 + 14 = 27
subtract 155
