Reorder the terms:
(100 + x)(x + 50) = 15000

Reorder the terms:
(100 + x)(50 + x) = 15000

Multiply (100 + x) * (50 + x)
(100(50 + x) + x(50 + x)) = 15000
((50 * 100 + x * 100) + x(50 + x)) = 15000
((5000 + 100x) + x(50 + x)) = 15000
(5000 + 100x + (50 * x + x * x)) = 15000
(5000 + 100x + (50x + x2)) = 15000

Combine like terms: 100x + 50x = 150x
(5000 + 150x + x2) = 15000

Solving
5000 + 150x + x2 = 15000

Solving for variable 'x'.

Reorder the terms:
5000 + -15000 + 150x + x2 = 15000 + -15000

Combine like terms: 5000 + -15000 = -10000
-10000 + 150x + x2 = 15000 + -15000

Combine like terms: 15000 + -15000 = 0
-10000 + 150x + x2 = 0

50 + -50 + -1x = 0 + -50

Combine like terms: 50 + -50 = 0
0 + -1x = 0 + -50
-1x = 0 + -50

Combine like terms: 0 + -50 = -50
-1x = -50

Divide each side by '-1'.
x = 50

Simplifying
x = 50
Solution
x = {-200, 50}
