1.
Find the volume of a cube with one edge (m - 3) long.
Volume=(m-3)³=(m-3)(m-3)(m-3)=m³-9m²+27m-27
2.
Simplify: (a - 4)(a² + 3a - 2).
(a-4)(a²+3a-2)=a³-a²-14a+8
3.
Expand and simplify: (p + 3)(p - 7).
(p + 3)(p - 7) = p² - 7p + 3p - 21 = p² - 4p - 21
4.
Expand and simplify: (f + 5g)(2f - 5g + 7).
(f+5g)(2f-5g+7)=2f²+5fg+7f-25g²+35g
5.
Expand and simplify: (h - 6)(h + 11).
(h-6)(h+11)=h²+11h-6h-66=h²+5h-66
