Solution for (20000-x)(10000-x)=100000000 equation:


Simplifying
(20000 + -1x)(10000 + -1x) = 100000000

Multiply (20000 + -1x) * (10000 + -1x)
(20000(10000 + -1x) + -1x * (10000 + -1x)) = 100000000
((10000 * 20000 + -1x * 20000) + -1x * (10000 + -1x)) = 100000000
((200000000 + -20000x) + -1x * (10000 + -1x)) = 100000000
(200000000 + -20000x + (10000 * -1x + -1x * -1x)) = 100000000
(200000000 + -20000x + (-10000x + 1x2)) = 100000000

Combine like terms: -20000x + -10000x = -30000x
(200000000 + -30000x + 1x2) = 100000000
