(-2x² + wx - 4) - (x² + 5x + 6) = -3x² - 10    Distribute/multiply - into (x² + 5x + 6)

-2x² + wx - 4 - x² - 5x - 6 = -3x² - 10      Combine like terms

-3x² + wx - 5x - 10 = -3x² - 10         Add 10 on both sides

-3x² + wx - 5x = -3x²               Add 3x² on both sides

wx - 5x = 0          Add 5x on both sides

wx = 5x        Divide x on both sides

w = 5

Solution for the question asked: 3x^2-5x+4=6


it can be simplified by subtracting 6 from both the sides...


3x^2-5x+4-6=6-6


3x^2-5x-2=0 which is the required form where a=3,b=-5 and c=-2.Now putting the values in the formula we will get two values for x which are 6 and (-1).

hope this will help you

A carnival game allows a group of players to each draw and keep a marble from a bag. The bag contains 5 gold marbles, 25 silver
laila [671]
1. What’s the probablity of a second person winning the small prize?
There are now 99 total marbles, and 24 silver marbles. So, 24/99 is 0.24 probability.
2. Which player is most likely to win a big prize?
Since each player draws a silver marble (aka a small prize) there are less small prize marbles in the bag after each turn. So, the first person would have a 5% chance (or 0.05)of winning the big prize gold marble, but the last person would have a slightly bigger chance (5.15% or 0.0515) of winning a big prize.
3. How could the game be made fair for each player?
Well it’s quite simple, just have each player return their marble and the number of marbles would be kept constant, giving everyone an equal chance. Or you could have them all play at the same time, either way.
4. Same answer as 3
