Question

Which two numbers have a difference of 5 and a product of 3.36???

Answer 1

x - y = 5

x.y = 3.36

$(x-y)^2=5^2$

$x^{2} -2xy + y^{2} =25$

$x^{2} + y^{2}=25+6.72=31,72$

$(x+y)^2= x^{2} +2xy+ y^{2} =31,72 + 6,72 = 38,44$

$\sqrt{(x+y)^2}= \sqrt{38,44}$

x+y= 6,2
 and we know that x - y= 5

x+y+x-y=6,2 + 5
2x=11,2
x=5,6

so then y=0,6

Answer:

x= 5,6
y= 0,6
