X^2+4x+4=8
-8                -8
subtract 8 from both sides 

x^2+4x-4=0

now factor using quadratic formula
ax^2+bx+c=0

x= -b +-[ (sqrt (b^2-4ac))/2a ]

x=-2(1+sqrt(2))


x= 2(sqrt(2) -1)

hope that helps, hopefully you know how to plug and chug into quadratic formula. if not you can ask for help

Answer: I can only see the big boxes so will answer them

5/6 - 1/3

Multiply the two denominators together get 18

Then multiply the bottom denominator with the opposite numerator

The sum has now changed to:

15/18 - 6/18

15 - 6 = 9

9/18 can then be simplified to 1/2

Fill in the blanks<br>864+2006=--------+864<br><br>5351 +(574+799)= 574+(5351+_____)​
Mama L [17]

Answer:

2006

799

Step-by-step explanation:

Given the expression:

The right hand side of the sun must be equal to the left hand side ;

Therefore ;

864+2006=--------+864

The sum of 864 and 2006 must be equal to the right hand side sum ; hence

864+2006= 2006 +864

Similarly, the left hand side and right havd side must also be equal here ;

5351 + 574 + 799 = 574 + 5351 + 799

Hence, the missing value is 799
