(x + 1)(x + 8)

x(x + 8) + 1(x + 8)

x*x + 8*x + 1*x + 1*8

x² + 8x + x + 8

x² + 9x + 8

Hope this explains it.

Evaluate the following expression:<br>p/-3 + (-8)= -8

aalyn [17]

P/-3+(-8)=-8
p/-3-8=-8
Add 8 to each side
p/-3-8+8=-8+8
p/-3=0
Multiply both side by 3
p/-3(3)=0(3)
p=0
Check:
p/-3+(-8)=-8
Substitute p with 0
0/-3+(-8)=-8
0-8=-8
-8=-8. As a result, p=0. Hope it help!
