Answer 2

Answer:

$1) \\ \\ {x}^{2} + 8x - 20 = {x}^{2} + 10x - 2x - 20 \\ \\ = x(x + 10) - 2(x + 10) \\ \\ = (x - 2)(x + 10). \\ \\ \\ 2) \\ \\ \\ \\ {x }^{2} - 6x - 16 = {x }^{2} - 8x + 2x - 16 \\ \\ = x(x - 8) + 2(x - 8) \\ \\ = (x + 2)(x - 8). \\ \\ \\ \\ \\ 3) \\ \\ \\ {x}^{2} - 6x + 8 = {x}^{2} - 4x - 2x + 8 \\ \\ = x(x - 4) + 2(x - 4) \\ \\ = (x + 2)(x - 4). \\ \\ \\ 4) \: \: \: \: \: \\ \\ {x}^{2} - 5x - 50 = {x}^{2} - 10x + 5x - 50 \\ \\ = x(x - 10) + 5(x - 10) \\ \\ = (x + 5)(x - 10). \\ \\ \\ \\ \\ 5) \\ \\ \\ \\ \\ {x}^{2} - 2x - 63 = {x}^{2} - 9x + 7x - 63 \\ \\ = x(x - 9) + 7(x - 9) \\ \\ = (x + 7)(x - 9). \\ \\ \\ \\ \\ 6) \: \: \\ \\ \\ \\ {x}^{2} - 7x + 10 = {x}^{2} - 5x - 2x + 10 \\ \\ = x(x - 5) - 2(x - 5) \\ \\ = (x - 2)(x - 5). \\ \\ \\ \\ 7) \\ \\ \\ \\ \\ {x}^{2} + 17x + 72 = {x}^{2} + 9x + 8x + 72 \\ \\ = x(x + 9) + 8(x + 9) \\ \\ = (x + 8)(x + 9). \\ \\ \\ \\ 8) \\ \\ \\ \\ {x}^{2} + 4x - 60 = {x}^{2} + 10x - 6x - 60 \\ \\ = x(x + 10) - 6(x + 10) \\ \\ = (x + 10)(x - 6). \\ \\ \\ \\ 9) \: \: \: \\ \\ \\ {x}^{2} + 18x + 80 = {x}^{2} + 10x + 8x + 80 \\ \\ = x(x + 10) + 8(x +1 0) \\ \\ = (x + 8)(x + 10). \\ \\ \\ 10) \\ \\ \\ \\ {x}^{2} + 5x + 6 = {x}^{2} + 3x + 2x + 6 \\ \\ = x(x + 3) + 2(x + 3) \\ \\ = (x + 2)(x + 3).$
