Question

if (a+b)=110 and ab=1089 then a^2+b^2=

Answer 1

Answer:

9922

Step-by-step explanation:

first find the factors of 1089 and then experiment to find which ones add up tp 110 which end up being 99 and 11. now plug the numbers in every equation to make sure the variables work for every one. :)

Answer 2

(a+b)^2=a^2+b^2 +2ab
(110)^2=a^2+b^2 +2*1089
12100= a^2+b^2 + 2178

a^2+b^2 = 12100-2178

a^2+b^2= 9922
