"the sum of the age of a mother and a daughter is 44 years. three years ago the product of their ages was 192.how old is the daughter now? plsssss show working"
Answered by R_Scott
m + d = 44 ... m = 44 - d

(m - 3)(d - 3) = 192 ... substituting ...(41 - d)(d - 3) = 192
... 41 d - d^2 -123 + 3 d = 192 ... d^2 - 44 d + 315 = 0

use the quadratic formula to find the ages
