What are the roots of the equation x^2-3x+1=0

Step-by-step explanation:

To find the roots of the equation, factor the equation and set each factor equal to 0 or use the quadratic equations. The quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=-3, and c=1

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
