Answer 2

Question :-

Product of two consecutive numbers is 72 what is the smallest number.

Answer :-

》》 Let the two consecutive numbers be x and x+1

Given ,

Their product is 72

So ,

$x(x+1) = 72\\</p><p>x^2 + x = 72\\</p><p>x^2 + x - 72 = 0\\</p><p>x^2 +9x-8x-72=0\\</p><p>x(x+9)-8(x+9)=0\\</p><p>(x+9)(x-8)=0$

if x+9 = 0

x = -9

if x-8 = 0

x = 8
