Transcribed Image Text:Simplify and write as a polynomial in standard form. (2x²+7x-30) (x+6) -(6x - 5)
Solution: 3x - 5; Video: https://www.loom.com/share/3380d1d4b923493db7f9601d8c5 3x²-17x+20 X-4 Dividing # X-4=0 X=4 4 3 ↓ -17 20 + 12 -20 3x - 5x 10 → Rem Constant * Quohent: 3x-5 * Because remainder is 0; 3x-5 and X-4 are factors of the dividend (3x-5)(x-4)= 3x²-17x+-20
