Answer:
x = 0/2
x = 0
Step-by-step explanation:
4(x+8)-2(x-7) = 46
Expanding the brackets
4x +32 - 2x +14 = 46
2x + 46 = 46
2x = 46-46
2x = 0
x = 0/2
x = 0
Answer:
3+sqrt(13/2)
3-sqrt(13/2)
Step-by-step explanation:
2 (x-3) ^2 =13
Divide each side by 2
2/2 (x-3) ^2 =13/2
(x-3) ^2 =13/2
Take the square root of each side
sqrt((x-3) ^2) =±sqrt(13/2)
x-3 = ±sqrt(13/2)
Add 3 to each side
x-3+3 = 3±sqrt(13/2)
x = 3±sqrt(13/2)
