Answer:
100 - 4q²
Step-by-step explanation:
(10 - 2q)(10 + 2q)
each term in the second factor is multiplied by each term in the first factor.
10(10 + 2q) - 2q(10 + 2q) ← distribute parenthesis
= 100 + 20q - 20q - 4q² ← collect like terms
= 100 - 4q²
Answer:
[tex]100-4q^{2}[/tex]
Step-by-step explanation:
[tex]\\(10-2q)(10+2q)\\=(10)(10)+10(2q)-2q(10)-(2q)^{2} \\=100+20q-20q-4q^{2} \\=100-4q^{2}[/tex]
