Identify the factor terms by grouping: 5x3 – 4x2 + 20x – 16
Elanso [62]
 5x3-4x2-20x+16=0 Three solutions were found : x = 4/5 = 0.800 x = 2 x = -2Reformatting the input :Changes made to your input should not affect the solution:
 (1): "x2"   was replaced by   "x^2".  1 more similar replacement(s).
Step by step solution :Step  1  :Equation at the end of step  1  :  (((5 • (x3)) -  22x2) -  20x) +  16  = 0  Step  2  :Equation at the end of step  2  :  ((5x3 -  22x2) -  20x) +  16  = 0 Step  3  :Checking for a perfect cube : 3.1    5x3-4x2-20x+16  is not a perfect cube 
Trying to factor by pulling out : 3.2      Factoring:  5x3-4x2-20x+16 
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1:  5x3+16 Group 2:  -4x2-20x 
Pull out from each group separately :
Group 1:   (5x3+16) • (1)Group 2:   (x+5) • (-4x)

The percent change in attendance, relative to last year's show is a 5% increase.

<h3>What is the percentage change in attendance? </h3>

The value of the percentage change in attendance can be determined by subtracting the number of people in this year's show from the number of people at last year's show. The result would be divided by the number of people at last year's show and multiplied by 100.

[(16,800 - 16,000)/16,000] x 100 = 5%
