In this problem, we're being asked to find two integers whose product is given in the first column and whose sum is given in the second column.
00:07
So let's start with row a.
00:09
So we want to find two integers whose product is negative 50, but when we add them together, we get five.
00:15
Well, i'm first thinking for two factors that multiply to 50, i'm thinking of 10 and 5.
00:21
In order to get a sum of 5, i would have to do positive 10 and negative 5.
00:25
And to check, 10 times negative 5 is negative 50, but 10 might have to be a sum of 5.
00:30
And as 5 is 5.
00:31
Perfect.
00:32
Now, let's go to row b.
00:34
So we need to figure out two integers.
00:36
When we multiply, we get 27, but when we add, we get negative 28...
