What 2 numbers multiply to - 63 and add up to 7

2 numbers multiply to - 63 and add up to 7

Forming the equation, we need to let

x = first number

y = second number

xy = - 63

x+y = 7 - - > y = - x + 7

x (-x + 7) = 63

-x^2 + 7x = 63

x^2 - 7x = - 63

x^2 - 7x + 63 = 0

From the equation above, you need to find the roots.

After getting the roots, then you can decide that those are the two numbers.
