Answer 1

1.

а) (а + 2)(3 + b)

б) (5m - 3n)(4f - 5k)

в) (a - 3b)(5m + 1)

г) (a - 3b)(5m - 1)

2.

а) 3(a + 2) + b(a + 2) = (a + 2)(3 + b)

б) 4f(5k - 3n) - 5m(5k - 3n) = (5k - 3n)(4f - 5m)

в) a(b + c + f) + (b + c + f) = (b + c + f)(a + 1)

г) x(a + b + c) - y(a + b + c) + z(a + b + c) = (a + b + c)(x + y + z)

3.

а) (2a + 3b)² + m(2a + 3b) + (2a + 3b) + m = m(2a + 3b + 1) + (2a + 3b)(2a + 3b + 1) = (2а + 3b + 1)(2a + 3b + m)

б) (3a + 6b)² + m(a + 2b)² = 9a² + 36ab + 36b² + m(a + 2b) = 9(a² + 4ab + 4b²) = 9(a + 2b) + m(a + 2b) = (a + 2b)(9 + m)
