Question

Given -15 and 44 are the sum and product of two numbers. Then the two numbers are

Answer 1

x+45/x =15 ; x^2+45 =15x ; x^2–15x+45=0 ;

x=15± √[225–4*1*45] /2 ; [15± √45]/2 ; [15±6.71] /2 =21.71/2 =10.855

or 4.145

if x=10.855 then y =15–10.855 =4.145 if x=4.145 then y 15–4.145=10.855

their sum of reciprocals =1/10.855 +1/4.145=0.092+0.241 =0.333
