SImplify the expressions.
1. x to the seventh times 1/x squared
2. (3 quaredx to the sixth)cubed
3. x to the nith/ x negitive squared
4. 15xsquaredy/ 6x to the fourthy to the fifth times 6xcubed y squared/5xy
USE direct substitution to evaluate the polynomial function for given x value.
5. f(x)= 4xcubed6xsquared+2x10 ; x=2
Use synthetic sub to evaluate th epolynomial function for the given vaule of x.
6. f(x)=8xto the fourth+5xcubed+4xsquaredx+7 ; x=1
perform th eindicated operation to simplify each polynomial, write all answers in standered form
7. (3xsquared5x+7)(2xsquared+9x1)
8. (5xcubed2xsquared+8x)+(5xsquared6)
9. (x+6)(x8)
10. 2xsquared(2xsquared+5x6)
11. (3x2)cubed
Factor each polynomaial completly
12. 64xcubed+343
13. 400xsquared25
14. x to the fouth+8xsquared9
15. 2xcubed3xsquared+4x6
Divide the polynomial function using long division
16. (12x cubed+31x squared17x6)/ (x+3)
Divide the polynomial function using synthetic division.
17. (x to the fourth+8xsquared2)/ (x+2)
