Answer:
the two numbers are 30 and 2
Step-by-step explanation:
form two equations ie. a+b=32
a*b=48
express b in terms of a ie. b=32-a
substitute that equation to the equation a*b=48
to form a*(32-a)=48
open the brackets to get 32a-a^2 =48
using the quadratic formula
round off your answer to get 30 and 2
