Answer:
1) (n+5)(n-1)
2) (n-4)(n+3)
3) (v-4)(v-1)
4) (p-4)(p+2)
5)(7x-10)(x+1)
6)(7n-1)(n-9)
Step-by-step explanation:
1) Factors of -5 that add up to 4
2) Factors of --12 that add up to -1
3) Factors of 4 that add up to -5
4) Factors of -5 that add up to 4
5) 7[tex]x^{2}[/tex]-3x-10
7[tex]x^{2}[/tex]+7x-10x-10
7x(x+1)-10(x+1)
(7x-10)(x+1)
6)7[tex]n^{2}[/tex]-64n+9
7[tex]n^{2}[/tex]-63n-n+9
7n(n-9)-(n-9)
(7n-1)(n-9)
