First find two factors that make x^2 which is x and x: (x ?)(x ?)
Then because the last number is (-)10, you now know that there is a positive and negative symbol: (x + ?)(x-?)
Lastly, you have to find two factors of 10 that when subtracted equal to positive 3. A +5 and -2 when multiplied will equal to -10, and when subtracted will make +3. Then you can use the FOIL method to double check. im sorry.. ive never done this before lolol
