CBSE Class 10 Answered

if x is a natural number and x(37+x)=308 find x
Asked by Amber Tanweer | 25 Jan, 2014, 08:59: PM
answered-by-expert Expert Answer

x(37+x) = 308

x2 + 37x - 308 = 0

x2 + 44x - 7x - 308 = 0

x(x+44) -7(x+44) = 0
(x - 7) (x+44) = 0
x = 7 or -44
 
Since, x is a natural number, so x = 7.
