What two numbers multiply to -126 and add up to -65
Airida [17]
Xy = -126
x + y = -65

xy = -126
\frac{xy}{x} = \frac{-126}{x}
y = \frac{-126}{x}

x + y = -65
x + \frac{-126}{x} = -65
\frac{x^{2}}{x} + \frac{-126}{x} = -65
\frac{x^{2} - 126}{x} = -65
-65x = x^{2} - 126
0 = x^{2} + 65x - 126
x = \frac{-(65) \+ \sqrt{(65)^{2} - 4(1)(-126)}}{2(1)}
x = \frac{-65 \± \sqrt{4225 + 504}}{2}
x = \frac{-65 \± \sqrt{4729}}{2}
x = \frac{-65 \± 68.8}{2}
x = \frac{-65 + 68.8}{2}  or  x = \frac{-65 - 68.8}{2}
x = \frac{3.8}{2}  or  x = \frac{-133.8}{2}
x = 1.9  or  x = -66.9

     x + y = -65
  1.9 + y = -65
- 1.9           - 1.9
           y = -66.9
    (x, y) = (1.9, -66.9)

or

        x + y = -65
  -66.9 + y = -65
+ 66.9        + 66.9
              y = 1.9
        (x, y) = (-66.9, 1.9)

The two numbers that add up to -65 and can multiply to -126 are the numbers -66.9 and 1.9.

What is the solution to this equation? 5(x - 6) + 4 = 7x - 4
dimaraw [331]

5(x - 6) + 4 = 7x - 4

5x - 30 + 4 = 7x - 4

5x - 26 = 7x - 4

5x - 26 + 4 = 7x

5x - 22 = 7x

-22 = 7x - 5x

-22 = 2x

-22 / 2 = x

-11 = x

x = -11 is the solution to the given equation
