(-2v-49)x(5v-100)
Multiply each term in the first parentheses by each term in the second parentheses (foil)
-2vx5v-2vx(-100)-49x5v-49 x (-100)
calculate the product
-10v²-2v x(-100)-49x5v-49 x(-100)
-2vx5v
Multiply the numbers
-10v x v
the same of the other one ok is different how i am doing
-2vx5v
If a term doesn't have an exponent , it is considered that the exponent is 1
-10v^ 1 x v
-10v^1 xv^1
Multiply the terms with the same base by adding their exponents
-10v^1 x v^1
-10v^1+1
to add the numbers using a number line, start from zero
1+1=2
Since 1 is positive, move the point 1 unit to the right
The result is 2
Answer: -10v^2
That's it . Hope it wasn't too hard to understand?
PLEASE MARK ME AS BRAINLIEST
