Step-by-step explanation:
STEP
1
: Equation at the end of step 1
(((5•(x3))+(3•(x2)))+1)-((2x3-x2)+3)
STEP 2 Equation at the end of step
(((5•(x3))+3x2)+1)-(2x3-x2+3)
STEP 3 :
Equation at the end of step
((5x3 + 3x2) + 1) - (2x3 - x2 + 3)
STEP

Polynomial Roots Calculator :
4.1 Find roots (zeroes) of : F(x) = 3x3+4x2-2
Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 3 and the Trailing Constant is -2.
The factor(s) are:
of the Leading Coefficient : 1,3
of the Trailing Constant : 1 ,2
Let us test ....
P Q P/Q F(P/Q) Divisor
-1 1 -1.00 -1.00
-1 3 -0.33 -1.67
-2 1 -2.00 -10.00
-2 3 -0.67 -1.11
1 1 1.00 5.00
1 3 0.33 -1.44
2 1 2.00 38.00
2 3 0.67 0.67
Hope This Helps
The mean can be calculated by adding all the summation of numbers and divide it by how many total numbers there are, such as shown below:
Add total allowances= $0(for 77 students) + $3 (for 55 students) + $5 (for 77 students) + $6 (for 33 students) + $8 (for 22 students)
Total allowances=$0+$3+$5+$6+$8 =$22
Total # of students = 77 + 55 + 77 + 33 +22 =264 students
Mean=Total allowances/total students
Mean=$22/264
Mean= $0.0833
