Which 2 numbers multiply to 36 and add up to -15?

Let the numbers be: x and y
Now, we will set up the equation with the variables and given info..
[tex]x \times y = 36 \\ x + y = - 15[/tex]
Solve using the substitution method
[tex]x \times y = 36 \\ x = - 15 - y[/tex]
[tex]( - 15 - y)\times y = 36[/tex]
[tex]y = - 12[/tex]
[tex]x = - 15 - ( - 12)[/tex]
[tex]x = - 3[/tex]
➪ Therefore, The two numbers are: -12 and -3
