To find two numbers that multiply to 225 and add up to -15, we can set up a system of equations. Let's call the two numbers x and y. We know that xy = 225 and x + y = -15. By factoring 225, we get 225 = 15 * 15 = 3 * 5 * 3 * 5. By examining the factors, we can see that -15 can be represented by -3 and -12. Therefore, the two numbers are -3 and -12.
Oh, dude, that's like a blast from the past with algebra. So, you're looking for two numbers that multiply to 225 and add up to -15. Those numbers are -15 and -10. Yeah, it's like math magic, but with more negativity.
For future reference, this can be done with simultaneous equations.
x + y = -15
xy=225
therefore x=-y-15
sub all in for x
y(-y-15) = 225
-y^2 - 15y -225=0
y^2 + 15y + 225 = 0
Unfortunately the solution to this is an imaginary number, i.e. it doesn't exist
