Verified answer
Answer:
1.) 6y(2y + 3)
Solution:
6y(2y + 3)
[tex]12 {y}^{2} + 18y[/tex]
2.) 7(-5y - 8)
Solution:
7(-5y - 8)
[tex] - 35y - 56[/tex]
3.) (2n + 2) (6n + 1)
Solution:
FOIL method
F = (2n) (6n) = [tex] 12{n}^{2} [/tex]
O = (2n) (1) = 2n
I = (2) (6n) = 12n
L = (2)(1) = 2
[tex]12 {n}^{2} + 2n + 12n + 2 \\ 12 {n}^{2} + 14n + 2 \\ (2)6 {n}^{2} + 7n + 1[/tex]
4.) (8p - 2) (6p + 2)
Solution:
F = (8p)(6p) = [tex]48 {p}^{2} [/tex]
O = (8p) (2) = 16p
I = (-2)(6p) = -12p
L = -2(2) = -4
[tex] {48p}^{2} + 4p - 4 \\ (4){12p}^{2} + p - 1[/tex]
5. (4a + 2)
[tex] {6a}^{2} - a + 2[/tex]
[tex](4a){6a}^{2} - a + 2 \\ {24a}^{3} - 4 {a}^{2} + 8a[/tex]
[tex](2){6a}^{2} - a + 2 \\ {12a}^{2} - 2a + 4[/tex]
[tex]24 {a}^{3} - 4 {a}^{2} + 12 {a}^{2} + 8a - 2a + 4 \\ 24 {a}^{3} + 8 {a}^{2} + 6a + 4 \\ (2)12{a}^{3} + 4 {a}^{2} + 3a + 2[/tex]
