Question

How do I solve this using long division?

Answer 1

(x - 2)(x + 5)

Explanation:

x +5

----------------------

x - 2 | x² + 3x - 10

x² - 2x ↓

------------------------

5x - 10

5x - 10

------------------------

0 ← remainder = 0

quotient = x + 5

Then x² + 3x - 10 = (x - 2)(x + 5 )

Answer 2

You can't.

Explanation:

When you divide it you get x+5.
