∙ 11y agoThe complex conjugate pair,
-2.5 - 11.565i
and
-2.5 + 11.565i
where i is the imaginary square root of -1.
They are: 4*5*7 = 140
How about: 4*5*7 = 140
what 2 numbers add to make five and multiply to make -36
There are no two real numbers that do, but the complex numbers (2 + i) and (2 - i) will.If you want two numbers that multiply to negative 5 and add to positive 4 then: -1 and 5If you want two numbers that multiply to negative 5 and add to negative 4 then: 1 and -5
0
Multiply: 0.43845 x 4.56155 = 2 Add 0.43845 + 4.56155 = 5
15
none
12 and 5
-9
-9
There is no such numbers.If you used 9 and -4 then you will get 5 when you add them but you will get -36 when you multiply them.
