Solve x2 + 2x = 4 for x by completing the square. x equals plus or minus square root of 5 plus 1 x equals plus or minus square r

steposvetlana [31]

Answer:

x equals plus or minus square root of 5 minus 1

Step-by-step explanation:

we have

$x^{2} +2x=4$

Divide by 2 the coefficient of the x-term

$2/2=1$

squared the number

$1^2=1$

Adds both sides

$x^{2} +2x+1=4+1$

$x^{2} +2x+1=5$

Rewrite as perfect squares

$(x+1)^{2}=5$

take the square root both sides

$x+1=(+/-)\sqrt{5}$

$x=(+/-)\sqrt{5}-1$

therefore

x equals plus or minus square root of 5 minus 1

20POINTS PLEASE HELP!!!!

Arlecino [84]

I believe the answer is C or $2036.12 because sh earns 2.37% a month, and there is 12 months in a year so you have to multiply that percentage by 12 to make it one year. Then it asked for 8 years, so since you know how much percentage there is for one year, you just multiply by 8. Then you multiply your answer by 6200, and add that result to 6200, which is how you get c or 2036.12.
