Answer 1

Resposta:

$a) {x}^{2} {y}^{2} - {a}^{2} \\ (xy {)}^{2} - {a}^{2} \\ \\ \\ b) {16x}^{2} - 64 \\ 16( {x}^{2} - 4) \\ 16(x - 2) \times (x + 2) \\ \\ c)100 {y}^{2} - \: 100 \\ 100( {y}^{2} - 1) \\ 100(y - 1) \times (y + 1) \\ \\ \\ d) {4a}^{2} - 121 \\ {2}^{2} {a}^{2} - {11}^{2} \\ (2a {)}^{2} - {11}^{2} \\ (2a - 11) \times (2a + 11) \\ \\ \\ e) {0}^{2} - 10000 \\ 0 - 10000 \\ - 10000 \\ \\ \\ f) {w}^{4} {z}^{4} - {a}^{4} {b}^{16} \\ ({w}^{2} {z}^{2} - {a}^{2} {b}^{8}) \times ({w}^{2} {z}^{2} + {a}^{2} {b}^{8}) \\ (wz - {ab}^{4} ) \times (wz + {ab}^{4} ) \times ({w}^{2} {z}^{2} + {a}^{2} {b}^{8})$
