Question

The product of 2 numbers is +15 and their difference is -8. What are the 2 numbers?​

Answer 1

Answer:

if the number are x and y

then

xy=15. *1

x-y=-8. *2

x=y-8. *3

by *1&3

y(y-8)=15

${y}^{2} - 8y = 15 \\ {y}^{2} - 8y - 15 = 0 \\ by \: quadratic \: equation \: formula \: it \: becomes \: 9.6or - 1.56$

x-y=-8

x=-9.56or. x=1.56

if y =-1.56 x equals -9.56and if

if y =-1.56 x equals -9.56and if if y=9.56. x equals 1.56
