the first one is already factored

7ab(3a + 7b^2)

(x+4)(x+2)

(x-2)(x-1)

2(x^2 - 4x + 4)
2(x-2)(x-2)

2. 21a^2b + 49ab^3
7ab(3a + 7b^2)

3. x^2 + 6x + 8
(x + 2)(x + 4) {Note: 2 + 4 = 6, 2(4) = 8}

4. x^2 – 3x + 2
(x - 2)(x - 1) {-1-2 = -3, (-1)(-2) = + 2}

5. 2x^2 – 8x + 8
2(x^2 - 4x + 4)
2(x - 2)(x - 2) = 2(x - 2)^2

7ab(3a+7b^2)

(x-2)(x-4)
(x-1)(x-2)
(2x-4)(x-2)

first one cannot be factored
