I don’t understand what are u saying pls translate
Let the numbers be x and y. Then xy = -30 and x+y = -3.
Solve xy = -30 for y: y = -30/x
subst. -30/x for y in x+y= -3: x - 30/x = -3
Multiply all 3 terms by x: x^2 - 30 = -3x, so x^2 + 3x - 10 = 0
Solve this quadratic equation for x. x: {-5, 2}
If x = -5, then x+y = -3 becomes -5 + y = -3, and y = 2.
You should check to determine whether x=2 is also correct. If it is, what is the corresponding y value?

Answer:
(x-5)(x+2)
Step-by-step explanation:
Hello there!
Your expression there has a highest power of
, so there will be two constants that you need to find.
Your last term is -10, so the constants will have a product of -10. Also your middle term is -3x, so the terms will add up to -3
-5 and 2 fit the mold.
Have a great day!
