3x² - 5x +2 = 3x² -3x-2x+2=3x(x-1) - 2(x-1)= (x-1)(3x-2)


(x-1)(3x-2)=0

x-1=0 or 3x-2=0

x=1 or x=2/3


Zeros are x=1, x=2/3.

$200 in the ratio 1:2:2 working out
gtnhenbr [62]

Answer: 40:80:80

Step-by-step explanation:

The ratio is 1:2:2. This means, for every 5, the money is split in a ratio of 1:2:2. Let’s calculate how many 5s there are in 200. 200 / 5 = 40. So, the money will be split in 1:2:2 every 5 dollars 40 times.

Excellent. So, we can easily find out the ratio by multiplying the ratio 1:2:2 by 40. 1*40:2*40:2*40 = 40:80:80. Let’s add these up, and see if they result in 200. 40 + 80 + 80 = 200. So, our answer is correct.

Hope this helps!
