Solution steps

(5 x + 7 y + 2) (x - 7 y + 2)

Distribute parentheses

= 5 xx + 5 x (- 7 y) + 5 x \cdot 2 + 7 y x + 7 y (- 7 y) + 7 y \cdot 2 + 2 x + 2 (- 7 y) + 2 \cdot 2

Simplify

5 xx + 5 x (- 7 y) + 5 x \cdot 2 + 7 y x + 7 y (- 7 y) + 7 y \cdot 2 + 2 x + 2 (- 7 y) + 2 \cdot 2 : 5 x^{2} + 12 x - 7 y^{2} - 47 x y + 4

= 5 x^{2} + 12 x - 7 y^{2} - 47 x y + 4
