Answer:
5x^2 -3x +9
Step-by-step explanation:
(5x2 + 7) - (3x - 2)
Distribute the minus sign
5x^2 +7 -3x +2
Combine like terms
5x^2 -3x +9
As order is not important in this problem, we make use of the concept of Combination. A group of 5 people should be picked out of the 8. In mathematical notation, the possible combinations (P) is 8C5. This is equal to 56. Thus, there are 56 different ways to which 5 people can be selected.
Answer:
x+3*1/x=52/7
7x^2/7x+21/7x=52x/7x
7x^2-52x+21=0
I solve this with the quadratic formula
Solution of ax^2+bx+c=0, a≠0 are :
x1= 
and x2= 
so a=7, b=-52,c=21
x1=
= (52+46)/14=98/14=7
x2=(52-46)/14=6/14=3/7
