How do you solve for (w-2)²-63=0 where w is a real number

Mathematics
1 answer:
Murrr4er [49]2 years ago
4 0
(w-2)^2 = 63

FOIL left hand side:
(w-2)^2 = w^2 - 4w + 4

So,
w^2 - 4w + 4 = 63
w^2 - 4w - 59 = 0

Then use quadratic equation to get values of w = 2 + 3*root(7) and w = 2 - 3*root(7).

¿Cuáles son los procedimientos a ambos lados de la igualdad que se deben realizar para calcular el valor de la incógnita x en la
PilotLPTM [1.2K]

Answer:

Los procedimientos que se deben realizar para calcular la incógnita x en la ecuación 2x+5=7 son:

  1. <u><em>El 5 que está sumando a la izquierda del igual, se pasa a restar a la derecha del igual.</em></u>
  2. <u><em>El 2 que multiplica a x a la izquierda del igual, se pasa a dividir a la derecha del igual.</em></u>

Step-by-step explanation:

Siguiendo los procedimiento descritos en la respuesta, para calcular el valor de la incógnita:

  • 2x + 5 = 7

Seguimos el primer paso: <em>el 5 que está sumando a la izquierda del igual, se pasa a restar a la derecha del igual</em>:

  • 2x = 7 - 5

Seguimos el segundo paso: <em>el 2 que multiplica a x a la izquierda del igual, se pasa a dividir a la derecha del igual:</em>

  • x=\frac{7-5}{2}

Como puedes ver, así se despejaría la incógnita x y solo faltaría operar los datos en la ecuación para obtener la respuesta:

  • x=\frac{2}{2}
  • x=1

<u><em>El resultado que nos daría la incógnita x sería 1</em></u>. Podemos probar el resultado en la ecuación original para comprobar el resultado que obtuvimos:

  • 2x + 5 = 7
  • 2 *(1) + 5 = 7
  • 2 + 5 = 7
  • 7 = 7

Así, identificamos que los procesos realizados fueron correctos.

The value of 2 in 2783 is what compared to the
kykrilka [37]
We Know That This Number Is:

Two-Thousand-Seven-Hundred-Eighty-Three.

So, This tells Us That The 2 Is The Thousandths Place.

So, We Also Know That The Value Of 2 In The 2nd One Is 200. This Means That The value of the first one is 10 times larger than the value of the 2 in the second one!

Sum of exterior angle of a polygon is 360
90 + 10x + 5x + 45 = 360
135 + 15x = 360
15x = 360 - 135 = 225
x = 225/15 = 15

Largest exterior angles = 10x = 10(15) = 150 degrees.
