Question

Can you factor y^2+49 using the differences of two squares form? Why or why not?

Answer 1

No you can't, because if you were to factor this furthur you wouldn't end up with y^2+49 when checking to see if your factorization works. This could work if the equation is y^2-49 because then when you factor it would look like this:

`{y}^(2) - 49 \\ (y - 7)(y + 7) \\`
