Answer:
c
Step-by-step explanation:
S=B+1/2Pl
-b from both sides
s-b=1/2Pl
x2 to both sides
2(S-B)=Pl
divide both sides by l
you get c
The answer is A. k/6 + 8 - 2/k
First lets distribute the 5x
5x^2 + 30x = -50
Lets divide every term by 5
x^2 + 6x = -10
To complete the square we have to half the b value, which in this case is 6. Then square it.
Half of 6 is 3, 3 squared is 9
Add that to both sides of the equation
x^2 + 6x + 9 = -1
Find the binomial squared
(x+3)^2 (If you're wondering how i got that please comment)
(x+3)^2 = -1
Take the square root of the equation of both sides
(x+3) = +/- i
x = -3 +/- i
x = -3 - i
and
x = -3 + i
