Factor
7x²-13x-2
if you read this: hi

The equation can be rewritten as:

Factor out a 7x from the first two terms:

Factor out a 1 from the last two terms:

Then we can rewrite this as the fully factored equation:

You can check that this answer is correct by multiplying them and distributing.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
