Answer:

Step-by-step explanation:
5 3/4 = 23/4
(23/4)2 = 46/8
46/8 - 5/8 = 41/8 = 5 1/8
The best thing to do here is to find 1%, then multiply this by 12.
72/100= 0.72
0.72*12= 8.64
Therefore, 12% of 72 is 8.64
Hope this helps :)
Eliminate parenthesis by using the distribution property
= 5x² -3x +3 - x² - 2x +1
Group similar terms
= (5-1)*x² + (-3 -2)*x + (3+1)
Then sum everything:
= 4x² -5x +4
