Use completing the square to solve the equation x2 - 10x = -8.

Kay [80]

Answer:

x^2 - 10x + 25 = 17

Step-by-step explanation:

Please use " ^ " to denote exponentation:

x^2 - 10x = -8

x^2 - 10x + 25 = 17

x^2 - 10x + 25 = -8

x^2 - 10x - 25 = -33

Begin with x^2 - 10x = -8. Here's the process for completing the square:

1. Take half of the coefficient of x and square the result:

(1/2)(-10) = -5, and then (-5)^2 = + 25

2. Add this 25 to the first two terms of x^2 - 10x = -8 and also to the constant -8: x^2 - 10x + 25 = -8 + 25, or x^2 - 10x + 25 = 17

3. Match this result to one of the given possible answers. Turns out that the given possible answer matching our result is the first one:

x^2 - 10x + 25 = 17

Solve the system by substitution. -4.5-2y=-12.5 , 3.35x-y=-0.75

goldenfox [79]

First, we solve for y in the first equation:
$-2y = -12.5 +4.5$
$-2y=-8$
$y= \frac{8}{2}$
$y=4$
Then, we substitute the y value in the other equation and solve for x:
$3.35x-(4)=-0.75$
$3.35x=-0.75+4$
$3.35x=3.25$
$x= \frac{3.25}{3.35}$
$x= \frac{65}{67}$
