Answer 1

1)-5,2)5,3)-5/2,4)2/3,5)0,6)

Answer 2

1) p(x)=x+5

p(x) =x+5=0

x=0-5

x=-5

2) p(x) =x-5

p(x) =x-5=0

x=0+5

x=5

3) p(x) =2x+5

p(x) =2x+5=0

x=-5/2

x=-2.5

4) p(x) =3x-2

p(x) =3x-2=0

x=2/3

5)p(x)=3x

3x=0

x=0/3

x=0

6)p(x)=ax=0

a is not zero. 0/any number=0

x=0/a

x=0

7)p(x)=cx+d

x=0=-d/c
