4. p2 - 2p - 3​

Answer 1

Answer:

heya mate ☺

$1) \: x ^{2} + 3x + 2 = 0 \\ = > x ^{2} + (2 + 1)x + 2 = 0 \\ = > x ^{2} + 2x + x + 2 = 0 \\ = > x(x + 2) + 1(x + 2) = 0 \\ = > (x + 2)(x - 1) = 0 \\ either \: x + 2 = 0 \\ = > x = - 2 \\ or \: x - 1 = 0 \\ = > x = 1 \\ \\ 2) \: p ^{2} - 2p - 3 = 0 \\ = > p ^{2} - (3 - 1)p - 3 = 0 \\ = > p ^{2} - 3p + p - 3 = 0 \\ = > p(p - 3) + 1(p - 3) = 0 \\ = > (p - 3)( p+ 1) = 0 \\ either \: p - 3 = 0 \\ = > p = 3 \\ or \: p + 1 = 0 \\ = > p = - 1$
