Last week, Jane made deposits of $64,$25 and $37 into her checking account. She then wrote checks for $52 and $49. What is the overall change in Jane's account balance?

$25 added to her account

Step-by-step explanation:

$25.00

Step-by-step explanation:

You add what she put in. Then add what she took out. Then subtract them.

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
