[tex]1. \: \: {x}^{2} - 2x - 15 = 0[/tex]
[tex]2. \: \: {x}^{2} - 5x - 14 = 0[/tex]
[tex]1. \: \: {x}^{2} - 2x - 15 = 0[/tex]
[tex]2. \: \: {x}^{2} - 5x - 14 = 0[/tex]
Jawaban:
PENYELESAIAN
[tex]1. \: {x}^{2} - 2x - 15 = 0[/tex]
[tex](x - 5)(x + 3) = 0[/tex]
[tex](x = 5)(x = - 3)[/tex]
[tex]hp = ( - 3.5)[/tex]
[tex]2. \: {x}^{2} - 5x - 14 = 0[/tex]
[tex](x - 7)(x + 2) = 0[/tex]
[tex](x = 7)(x = - 2)[/tex]
[tex]hp = ( - 2.7)[/tex]
