\(11)~c^2-c-6=(c+2)(c-3)\\\\ 12)~x^2+19x+78=(x+6)(x+13)\\\\ 13)~m^2-6mn-27n^2=(m+3n)(m-9n)\\\\ 14)~x^3+16x^2+64x=x(x^2+16x+64)=x(x+8)^2\\\\ 15)~3x^3-9x^2-30x=3x(x^2-3x-10)=3x(x+2)(x-5)\\\\ 16)~4a^2+4ab-80b^2=4(a^2+ab-20b)=4(a-4b)(a+5b)\)

  1. \(c^{2} -c-6\\(c-3)(c+2)\)
    c = 3 and c = -2

    12. \(x^{2} +19x+78\\(x+6)(x+3)\)
    x = -6 and x = -3

    13. \(m^{2} -6mn-27 n^{2} \\ (m-9n)(m+3n)\) 
    m = 9n and m = -3n
    \(n= \frac{-m}{9}\) and \(n= \frac{m}{3}\)

    14. \(x^{3} +16 x^{2} +64x\\ (x)(x+8)(x+8)\)
    x = 0 and x = -8

    15. \(3 x^{3} -9 x^{2} -30x\\ (3x)(x+2)(x-5)\)
    x = 0, x = -2, and x = 5

    16. \(4a^{2}+4ab-80b^{2} \\ 4(a+5b)(a-4b)\)
    a = -5b and a = 4b
    \(b= \frac{-a}{5}\) and \(b= \frac{a}{4}\)
