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)
The lowest number is 3.
3 x 588 = 1,764
1,764 = (42) squared
I don't know an easy way to do it. I just slogged through it one-by-one ...
I tried 2 , then I tried 3 and I didn't have to go any farther.
You could have done the same thing. The difference between us is that
I'm willing to work on it just for fun, whereas you're not willing to work on it
even for homework. That's why I became good in math and you might not.
Answer:
option C is your right answer
Step-by-step explanation:
have a nice day!!
7x^2 - 16x - 8 = 0
using the quadratic formula x = [ -(-16)+/- sqrt((-16^2 - 4*7-8] / 2*7
= (16 +/1 sqrt 480) / 14
= 2.71, -0.42 to nearest hundredth
