Question

tell me two numbers which when added gives you -12 and when multiplied gives 4​

Answer 1

Answer:

Step-by-step explanation:

A+B=-12

AB=4

(A+B)∧2=(A-B)∧2+4AB

AFTER SOLVING BY THIS FORMULA YOU WILL GET ANSWER

Answer 2

$x + y = -12$ this is equation 1

$xy = 4$

$y = 4/x$ this is equation 2

from equation 1 & 2

$x + 4/x = -12\\x^2+4 = -12x\\x^2+12x+4 = 0\\by solving  this equation we get x = approx. -11.657  or -0.343$

$y= \frac{4}{x}$

when x = -11.657, $y = \frac{4}{-11.657}$

when x = -0.343, $y = -4/0.343$
