The product would be 250 because 7x50is 350 and the least 3 digit multiple of 10 would be 100. 350-100=250
Answer:

Step-by-step explanation:
We have been given an equation
. We are asked to find the solutions of our given equation.
We will use splitting the middle term method to solve quadratic equation.
We will split middle term of our given equation into parts such that whose product is
and whose sum is 3.
We know that such two numbers are
.




Using zero product property, we will get:



Therefore, the solutions for our given equation are
.
The second and fourth one are rational. They are perfect squares and are terminating or are fractions
The answer is 128. Sorry I’m really bad at explaining
