Which two numbers add up to -24 and multiple to -24

Answers

Answer 1

Answer: x + y = -24
xy = -24

$xy = -24$
$(xy)/(x) = (-24)/(x)$
$y = (-24)/(x)$

$x + y = -24$
$x + (-24)/(x) = -24$
$(x^(2))/(x) + (-24)/(x) = -24$
$(x^(2) - 24)/(x) = -24$
$-24x = x^(2) - 24$
$0 = x^(2) + 24x - 24$
$x = \frac{-(24) \± \sqrt{(24)^(2) - 4(1)(-24)}}{2(1)}$
$x = (-24 \± √(576 + 96))/(2)$
$x = (-24 \± √(672))/(2)$
$x = (-24 \± 4√(42))/(2)$
$x = -12 \± 2√(42)$
$x = -12 \± 2(6.5)$
$x = -12 \± 13$
$x = -12 + 13$ $or$ $x = -12 - 13$
$x = 1$ $or$ $x = -25$

  x + y = -24    or      x + y = -24
  1 + y = -24 or -25 + y = -24
- 1   - 1 + 25 + 25
y = -25     or    y = 1
  (x, y) = (1, -25) or (x, y) = (-25, 1)

The two numbers that add up to 24 are the numbers 1 and -25.

$y = (-24)/(x)$

$x + y = -24$

$x = \frac{-(24) \± \sqrt{(24)^(2) - 4(1)(-24)}}{2(1)}$
$x = (-24 \± √(576 + 96))/(2)$
$x = (-24 \± √(672))/(2)$
$x = (-24 \± 4√(42))/(2)$
$x = -12 \± 2√(42)$
$x = -12 \± 2(6)$
$x = -12 \± 12$
$x = -12 + 12$ $or$ $x = -12 - 12$
$x = 0$ $or$ $x = -24$

  x + y = -24    or      x + y = -24
  0 + y = -24 or -24 + y = -24
- 0 - 0 + 24 + 24
y = 24    or    y = 0

The two numbers that multiply to -24 are the numbers 24 and 0.
