#1}5c to the 2nd power plus 2c to the 2nd power minus 3c to the 2nd power plus 4c to the 2nd power

#2}15m cube over 5m

#3}{3x}{2x 2nd power y}{2y}

#4}{n+2}{3n-5}

#6} solve 3x to the 2nd power plus 15=0

#10}i 39 power

#12}125 one-third power

#13} express 0.00000068 in scientific notation

#14}evaluate{8 times 10negative4power}{3.5 times 10 to the 9th power}. express answer in scientific notation.

#15} factor. x to the 2nd power minus 9x plus 18

#16} n to the 2nd power minus 144

#17} 25x to the 2nd power minus 30xy plus 9y to the 2nd power

#18} 2xcube minus 2xsquare

#19}csquare plus 6c minus 7


THIS ISN'T ALL OF THEM BUT IF U COULD E-MAIL THESE ANSWERS IT WOULD REALLY BE APPRECIATED THANX :-D


Answer
1. 5c^2 _2c^2 +3c^2 +4c^2 = 14c^2
2. 15m^3/(5m) = 3m^2
3. (3x)(2x^2y)(2y) = 12x^3y^2
4. n^2 -n -10
6. 3x^2 +15 = 0, x^2 = -5, x = +/- i(5^1/2)
10. i^39 = -i
12. (125)^1/3 = 5
13. 6.8x10^-7
14. (8x10^-4)(3.5x10^9) = 2.8x10^6
15. x^2 -9x +18 = (x-3)(x-6)
16. n^2 -144 = (n+12)(n-12)
17. 25x^2 -30xy +9y^2 = (5x-3y)^2
18. 2x^3 -2x^2 = 2x^2(x-1)
19. c^2 +6c -7 = (c+7)(c-1)
I hope you've learned something from this
