X ^ 7 * (- x ^ 2) ^ - 3 3x (2x 6) - (x-3) (x 2) where x = 2

X ^ 7 * (- x ^ 2) ^ - 3 3x (2x 6) - (x-3) (x 2) where x = 2

X^7*(-X^2)^-3
=-x^7*x^-6
=-x
3X(2x+ 6)-(x-3)(x+ 2)
=-6x²+18x-x²+x+6
=-7x²+18x+6
=-7x2²+18x2+6
=-28+36+6
=14

(x-4)(2x-5)-(3x-2)(x+6)

Original form
=2x²-13x+20-（3x²+16x-12）
=-x²-29x+32

(2x-5)/6>3x-(x+2)/4

（2x-5)/6>3x-(x+2)/4
Multiply both sides by 12
2（2x-5)＞36x-3(x+2)
4x-10＞36x-3x-6
33x-4x＜-10+6
29x＜-4
x＜-4/29

3x + 6 × 2.5 = 16-x equation
