Question

1. A = (x-10)²

2. M = (2x + 5)²

Answer 1

Respuesta:

1. A= (x-10)²

x = [tex]\sqrt{A}[/tex] + 10 ,  x = - [tex]\sqrt{A\\}[/tex] + 10

2. M = (2x + 5)²

x = [tex]\frac{\sqrt{M-5} }{2}[/tex] ,      x = [tex]\frac{-\sqrt{M-5} }{2}[/tex]

Explicación paso a paso:

1. = (x-10)² = A

  = x - 10 = [tex]\sqrt{A\\}[/tex]  →  x = [tex]\sqrt{A\\}[/tex] + 10

  = x - 10 = - [tex]\sqrt{A}[/tex]  →  x = - [tex]\sqrt{A}[/tex] + 10

  x = [tex]\sqrt{A}[/tex] + 10, x = - [tex]\sqrt{A\\}[/tex] + 10

2. = (2x + 5)² =M

   = 2x + 5 = [tex]\sqrt{M}[/tex]  →  x = [tex]\frac{\sqrt{M-5} }{2}[/tex]

   = 2x + 5 = - [tex]\sqrt{M}[/tex]  →  x = [tex]\frac{-\sqrt{M} -5}{2}[/tex]

   x= [tex]\frac{\sqrt{M-5} }{2}[/tex] ,      x = [tex]\frac{-\sqrt{M-5} }{2}[/tex]
