Answer:

(x -5)(x +2)

Step-by-step explanation:

x² - 3x - 10

Sum = - 3

Product = -10

Factors = -5 , 2  {-5 +2 = -3  & (-5)*2 = -10}

x² - 5x + 2x - 10 = x(x -5 ) + 2(x - 5)

                          = (x - 5)(x + 2)

Answer:

[tex] {x}^{2} - 3x - 10[/tex]

[tex] {x}^{2} + 2x - 5x - 10[/tex]

[tex]x(x + 2) - 5(x + 2)[/tex]

[tex](x - 5)(x + 2)[/tex]
