Question

What are the 2 factors that multiply 15000 and adds up to 5

Answer 1

the answer is 125 and -120 gthe thing is 15000 is positive

Answer 2

ok so there are no real solutions for xy=15000 and x+y=5
there are immaginary solutions though so

xy=15000
x+y=5


x+y=5
y=5-x

x(5-x)=15000
-x^2+5x=15000
0=x^2-5x+15000
quadriacic formula
if ax^2+bx+c=0, then
x=$\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}$

x^2-5x+15000
a=1
b=-5
c=15000
x=$\frac{-(-5)+/- \sqrt{(5)^{2}-4(1)(15000)} }{2(1)}$
x=$\frac{5+/- \sqrt{25-60000} }{2}$
x=$\frac{5+/- \sqrt{-59975} }{2}$
x=$\frac{5+/- 5i\sqrt{2399} }{2}$
so the numbers are
$\frac{5+ 5i\sqrt{2399} }{2}$ and $\frac{5- 5i\sqrt{2399} }{2}$
