Option 1 : -22
using formula
(a + b )(a - b ) = a^2 - b^2
(√10 + 2√8) (√10 - 2√8)
= (√10)^2 - (2√8)^2
= 10 - 2×2×8=10-32
= -22
2nd question answer is option 3

Answer:
yes
yes is answer of this equation
Answer:
v=0
Step-by-step explanation:
Solve what is in the parentheses, then the exponents: 12v+10=64v+10
Subtract 64v from both sides: -52v+10=10
Subtract 10 from both sides: -52v=0
Divide by -52: v=0
