# Math Help - Difference of squares

1. ## Difference of squares

Use the difference of squares method to factorize 4819.

2. Hello, meshel88!

Use the difference of squares method to factor 4819.

I'm not familiar with the "difference of squares method",
. . but I solved it anyway . . .

I saw that: . $4819 \;=\;4900 - 81 \;=\;70^2 - 9^2$

Therefore: . $4819 \;=\;(70-9)(70+9) \;=\;61\cdot79$

Is that the method?
