What two numbers add/subtract to make negative 24 and multiply to make 16?
um none use the quadratic formula
There are no numbers that add or subtract to make negative 24 and multiply to get 16. This is because the numbers that can multiply to get 16 are 4 by 4 or 8 by 2 or 16 by 1and therefore when added or subtracted do not add up to 24.
X+y=-24. Xy=16. Y=-24-x. X(-24-x)=16. -24x+x^2=16. X^2-24x-16=0. X=(24+-sqrt(24^2-4(1)(-16)) / 2(1). X=solve the above (quad formula). Ck the results....obviously both numbers are neg
