Представте выражение в виде произведения:
a(a+b)-5b(a+b)
3a(a+z)+(a+z)
a(a+b)-5b(a+b) = (a+b)*(a-5b)
3a(a+z)+(a+z) = (a+z)*(3a+1)
a(a+b)-5b(a+b)= (a+b)^2*(a-5b)3a(a+z)+(a+z)= (a+z)^2*3a

a(a+b)-5b(a+b) = (a+b)*(a-5b)
3a(a+z)+(a+z) = (a+z)*(3a+1)
a(a+b)-5b(a+b)= (a+b)^2*(a-5b)
3a(a+z)+(a+z)= (a+z)^2*3a
