What is the coefficient of the fourth power of a - the square of 2a, the square of B + the fourth power of B, the number of times and the number of terms
It should be that the coefficients of each term are 1, - 2,1 respectively; the number of times is 4 and the number of terms is 3
The square of 4x-3 and the fourth power of a-2a, the square of B + the fourth power of B
By the way, the score is over 20
The coefficient 4x & # 178; - 3 is the number of terms 2 to the power of 4
The fourth power of a - the square of 2a, the square of B + the fourth power of B = (A & # 178; - B & # 178;) &# 178; = (a-b) &# 178; (a + b) &# 178;
