Use a quadratic equation to find two real numbers with the sum of 2 and a product of -24

The two real numbers with the sum of 2 and a product of -24  is 6 and -4.

Step-by-step explanation:

Let on of the number is k.

⇒ The other number is ( 2 -  k)

Now, product of the numbers  = -24

⇒  First Number x Second Number = -24

or,  k x  (2-k)  =  -24

or,

or,

or, (k-6)(k+4) = 0

⇒(k-6) = 0  or  (k  +4)  = 0

⇒ k  =  6 , or k = -4

Now, if k = 6, then other number is ( 2 - k ) = -4

And if k = -4, then other number is ( 2-k) = -6

Hence, the two real numbers with the sum of 2 and a product of -24  is 6 and -4.

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
