=9+8
=17

Given that the square of (a + 2) multiplied by 3 and the square of | B-1 | are opposite to each other, find the value of the third power of a minus the 2010 power of B

A = - 2, B = 1, the third power of a minus the 2010 power of B is - 9

How to calculate B [x / x square - 6x plus 9 greater than 0]

Is it X / X & # 178; - 6 (x + 9) > 0?
Obviously, X is not equal to 0
So the original formula multiply X by 178; left and right, and then shift the term
x＞6x²（x+9）
The result is 6x & # 179; + 54x & # 178; - x < 0
x（6x²+54x-1）＜0
By decomposing the factor, let x (6x & # 178; + 54x-1) = 0, three solutions of X can be obtained
The pinprick method is used to solve the inequality (on the hollow point of the number axis, the three solutions are pinpricked from the top right, the biggest solution will go to the bottom, and then the second largest solution will go through the bottom, and then go through it.)
Then draw a straight line through X = 0, and the needle will be divided into two pieces, including x = 0
