Answer:

[tex]2(a+3)(a+3)[/tex]

[tex]5(x+1)(x-1)[/tex]

[tex]3t(t-2)(t+8)[/tex]

[tex]n(2+n)(2-n)[/tex]

Step-by-step explanation:

Factor each expression

[tex]2a^2 + 6a + 18[/tex]

[tex]2(a^2 + 3a + 9)[/tex]

product =9 and sum =6

3 times 3 is 9

3 plus 3 is 6

[tex]2(a+3)(a+3)[/tex]

2. Factor completely: 5x^2 − 5

GCF is 5

[tex]5x^2 - 5[/tex]

[tex]5(x^2 - 1)[/tex]

[tex]5(x+1)(x-1)[/tex]

3. Factor completely: 3t^3 + 18t^2 − 48t

[tex]3t^3 + 18t^2 -48t[/tex]

[tex]3t(t^2 + 6t -16)[/tex]

product is -16 and sum is 6

-2 times 8 = -16

-2+8=6

[tex]3t(t^2 + 6t -16)[/tex]

[tex]3t(t-2)(t+8)[/tex]

4. Factor completely: 4n − n^3

[tex]n(4 -n^2)[/tex]

[tex]n(2+n)(2-n)[/tex]
