### Question Description

1. (8x^4+9x^6+4)+(7x^5-2)-(-4x^5+6x^6+4x^4)

2. elimination method 3x+6y=13   and 15x+30y=65

3. 8x^8-12x^4/-2x^8

School: UIUC   Firstly please edit your answer for quadratic formula calculation which is t = 2.523.

1. (8x^4+9x^6+4)+(7x^5-2)-(-4x^5+6x^6+4x^4)

= 8x^4 + 9x^6 + 4 + 7x^5 - 2 + 4x^5 - 6x^6 - 4x^4

= 3x^6 + 11x^5 + 4x^4 +2

Elimination method 3x+6y=13   and 15x+30y=65

3x + 6y = 13 ................ Eq.1

15x + 30y = 65 ............ Eq.2

Multiply 1 by Eq.1 by 5

15x +30y = 65

There is no possible solution available for above Eq.1 and Eq.2

Solve: 8x^8-12x^4/-2x^8

= 8x^2 -12x^4/-2x^8

= -4x^-6 +6x^-4

Tutor went the extra mile to help me with this essay. Citations were a bit shaky but I appreciated how well he handled APA styles and how ok he was to change them even though I didnt specify. Got a B+ which is believable and acceptable. Brown University
