It is known that a and B are opposite to each other, C and D are reciprocal to each other, and the absolute value of X is 2. Find the value of X2 - (a + B + CD) x + (- CD) 2011

It is known that a and B are opposite to each other, C and D are reciprocal to each other, and the absolute value of X is 2. Find the value of X2 - (a + B + CD) x + (- CD) 2011

When x = 2, the original formula = 22 - (0 + 1) × 2 + (- 1) 2011 = 4-2-1 = 1; when x = - 2, the original formula = (- 2) 2 - (0 + 1) × (- 2) + (- 1) 2011 = 4 + 2-1 = 5. So the value of X2 - (a + B + CD) x + (- CD) 2011 is 1 or 5

How to find the cubic power of M - 3 times the square of M + 2 less than 0
emergency

M is less than 3

If a and B are opposite to each other, m and N are reciprocal to each other, and the square of K is equal to 4, then the value of 100A + 99b + MNB + K2 is ()
A. -4B. 4C. -96D. 104

∵ a, B are opposite numbers to each other, ∵ a + B = 0, ∵ m, n are reciprocal numbers to each other, ∵ Mn = 1, and the square of ∵ K is equal to 4, ∵ original formula = 100A + 99b + B + 4 = 100A + 100b + 4 = 100 (a + b) + 4 = 0 + 4 = 4
