Question

What t2o numbers multiply together to equal -15 and add together equal -2?

Answer 1

The two numbers are -5, 3. Which are multiply together to equal -15 and add together equal -2.  

Step-by-step explanation:

Step:1

      Let, X,Y.

      Where X, Y are two numbers.

Step:2

      Form the Multiplication equation from given,

      X×Y=-15 (∵ Multiply to equal -15)

Step:3

     Form Addition equation from given,

      X+Y= -2 (∵ Add equal to -2)

Step:4

      Check for alternatives to satisfy both equations

      Assume, X=1, Y=-15

      -15+1 = -14 (Not Satisfy addition equation)

      1×(-15)= -15 (Satisfy multiplication equation)

      Assume, X=15, Y=-1

      -1+15= 14 (Not Satisfy addition equation)

      (-1)×15= -15 (Satisfy multiplication equation)

  similarly.,

      assume X=-5, Y=3

      -5+3= -2 (Satisfy addition equation)  

      (-5)×3= -15 (Satisfy multiplication equation)

      So, the two numbers are -5,3.
