Algebra question help please

Question

x + y = x y = 5 , then x² y + x y² = ........

Help me please find the answer

Answer 1

x+y = 5, XY = 5

y = 5-x

x(5-x) = 5

5x -x^2 = 5

x^2 -5x +5 = 0

x = 5/2 +/- .5sqr(25 -20) = (5+/-sqr5)/2 = about (5+/-2.2)/2 = .about 1.4 or 3.6

y = about 3.6 or 1.4 (x,y) = (1.4, 3.6) or (3.6, 1.4)

x^2y + y^2x = (1.4)5 + 3.6(5) = 25
