De las soluciones de la siguiente ecuación: x2 + 8x − 30 = 18? Cual es el numero de mayor valor Entre.
vekshin1

Answer:

The correct answer is "x = 4" and "x = -12".

Step-by-step explanation:

The given equation is:

⇒  x^2+8x-30=18

On subtracting "18" from both sides, we get

⇒  x^2+8x-30-18=18-18

⇒  x^2+8x-48=0

On applying factorization, we get

⇒  x^2+12x-4x-48=0

On taking common, we get

⇒  x(x+12)-4(x+12)=0  

⇒  (x-4)(x+12)=0

⇒                 x-4=0

                          x=4

or,

⇒               x+12=0

                         x=-12

Set up an equation to show (×+2)×5=y
Masteriza [31]
<span>5x+10 = y

Subtract 10 from both sides.

5x = y - 10

Divide both sides by 5.

x = 1/5y - 2

Plugin 1/5y - 2 for the y.
5(1/5y - 2)
1 - 10 + 10 = y

1 = y
