Answer 1

$2) \: {x}^{2} - 22x + 117 \\ = {x}^{2} - 13x - 9x + 117 \\ = x(x - 13) - 9(x - 13) \\ = (x - 13)(x - 9) \\ \\ \\ 4) {z}^{2} + 19z - 150 \\ = {z}^{2} + 25z - 6z - 150 \\ = z(z + 25) - 6(z + 25) \\ = (z + 25)(z - 6) \\ \\ \\ 6) {y}^{2} - 6y - 135 \\ = {y}^{2} - 15y + 9y - 135 \\ = y(y - 15) + 9(y - 15) \\ = (y - 15)(y + 9)$
