Question

Find two numbers whose sum is 17 and product is -60(the formula is the one by which -60 was obtained)
$- 3\sqrt{5} \times 4 \sqrt{5}$
Please its Urgent..
Please answer correctly..If you don't know the answer please let someone who knows the answer to answer the question...

Answer 1

Step-by-step explanation:

Let first no. be x

Let second no. be y

Sum: x+y=17

: x=17-y

Product: x.y=-60

put value of x

(17-y).y=-60

17y-y²=-60

y²-17y+60=0

y²-12y-5y+60=0

y(y-12)-5(y-12)=0

(y-5) (y-12)=0

y-5=0, y=5

y-12=0, y=12

x+y=17

x+5=17 (Choose any value of y ,i take 5)

x=17-5

x=12

Therefore,x=12 y=5

Answer 2

Answer:

$- 3 \: \sqrt{5 \: \: \: \ 4 \sqrt{5} }$

ok..As the Above person Said..I really don't Get it. my Answer was -60.ok.um.Here you go according to me:-

$- 3 \: \sqrt{5} \: \times 4 \: \sqrt{5}$

$3 \times 5 \times 4$

$cause.. \sqrt{5} \sqrt{5} = 5$

$so...3 \times 5 \times 4$

$= - 60 \: is \: your \: answer$
