Question

1. A = (x-10)²

2. M = (2x + 5)²

Answer 1

Respuesta:

1. A= (x-10)²

x = $\sqrt{A}$ + 10 ,  x = - $\sqrt{A\\}$ + 10

2. M = (2x + 5)²

x = $\frac{\sqrt{M-5} }{2}$ ,      x = $\frac{-\sqrt{M-5} }{2}$

Explicación paso a paso:

1. = (x-10)² = A

  = x - 10 = $\sqrt{A\\}$  →  x = $\sqrt{A\\}$ + 10

  = x - 10 = - $\sqrt{A}$  →  x = - $\sqrt{A}$ + 10

  x = $\sqrt{A}$ + 10, x = - $\sqrt{A\\}$ + 10

2. = (2x + 5)² =M

   = 2x + 5 = $\sqrt{M}$  →  x = $\frac{\sqrt{M-5} }{2}$

   = 2x + 5 = - $\sqrt{M}$  →  x = $\frac{-\sqrt{M} -5}{2}$

   x= $\frac{\sqrt{M-5} }{2}$ ,      x = $\frac{-\sqrt{M-5} }{2}$
