Answer:
i dont get what its asking lol
Step-by-step explanation:
<em>2x³ + 17x² - 5</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>6x³ + 5x² + 3 – 4 (x³ – 3x² + 2) =</em>
<em>= 6x³ + 5x² + 3 - 4x³ + 12x² - 8</em>
<em>= 6x³ - 4x³ + 5x² + 12x² + 3 - 8</em>
<em>= 2x³ + 17x² - 5</em>
<em>Good luck !</em>
Answer:
2nd option
Step-by-step explanation:
trinomial is 2x² + 10x -4 = 0
a = 2
b = 10
c = -4
(-b±√b²-4ac) / 2a
= [-10±√100-4(2)(-4)] / 2
= (-10±2
) / 4
= (-5+)/2, = (-5-)/2 (simplified)
