x^2-2x-15= (x-5)(x+3)


x => -5


x => +3


(x+3)(x-2)/(x-5)(x+3)

Sam says 90 ÷ (–9) = 10. Is he correct? Use the drop–down menus to explain your answer.
SashulF [63]

Answer:

No.

Step-by-step explanation:

Sam is incorrect because if you look at the original problem, you'll see that he has missed the negative sign!

90 / 9 does equal 10, but 90 / -9 equals -10.

The only way to get a positive answer is if both the divisor and dividend are positive or if they are both negative.

Thus, the correct answer should be -10.
