For this case we have a factored expression, of a second degree equation:

([tex](x-3) (x + 8) = 0[/tex]

To find the solutions:

  • [tex]x-3 = 0[/tex]

we add 3 to both sides of the equation:

[tex]x=3[/tex]

  • [tex]x+8=0[/tex]

We subtract 8 on both sides of the equation:

[tex]x = -8[/tex]

Thus, the solutions of the equation are:

[tex]x_ {1} = 3\\x_ {2} = - 8[/tex]

Answer:

[tex]x_ {1} = 3\\x_ {2} = - 8[/tex]
