Answer 1

Answer:

$x ^{2} - 3x - 10 = 0$

Answer 2

$(a) \\ x {}^{2} - 3x - 10 = 0 \\ = > x {}^{2} - 5x + 2x - 10 = 0 \\ = > x (x - 5) + 2(x - 5) = 0 \\ = > (x - 5)(x + 2) = 0$

$(b) \\ 2x {}^{2} + x - 6 = 0\\ = > 2x {}^{2} + 4x - 3x - 6 = 0 \\ = > 2x(x + 2) - 3(x + 2) = 0 \\ = > (2x - 3)(x + 2) = 0$
