b) 5ab - 15a

c) 3m + mx - 3n - nx

d) 6x + xy + 6z + zy

Answer 1

$question = \\ a) 4x + 2y +10z \\ b) 5ab - 15a \\ c) 3m + mx - 3n - nx \\ d) 6x + xy + 6z + zy \\ solution. \\ a) = 4x + 2y +10z \\ = 2(2x + y + 5z)answer \: \\ \\ b) = 5ab - 15a \\ = 5a(b - 3) \: answer \\ \\ c) = 3m + mx - 3n - nx \\ = m(3 + x) - n(3 + x) \\ =( 3 + x)(m - n) \: answer \\ \\ d) = 6x + xy + 6z + zy \\ = x(6 + y) + z(6 + y) \\ = (6 + y)(x + z) \: answer \\ hope \: \: its \: \: help \: \: you$
