zeros of polynomials

 $\left(x+5\right)$  is one of the factors of   $x^3-4x^2-25x+100$   , find the roots. (Write it as x =   and write from smallest root to biggest.)

NOTE: DO NOT PUT SPACES

Determine the number of times that the graph of the polynomial will cross or touch the x-axis.
 $p\left(x\right)=\left(x^2-1\right)\left(x^2+7x+10\right)$  

Find the zeros of the polynomial.
 $p\left(x\right)=\left(x^2-36\right)\left(x^2-12x+27\right)$
