When (x+1)^4 is expanded and like terms are combined what is the coefficients of x^2

Step-by-step explanation:

Expand (x + 1)⁴:

The coefficient of x² is 6

(x+1)^4

(x+1)²(x+1)²

(x²+2x+1)(x²+2x+1)

x²(x²+2x+1)+2x(x²+2x+1)+1(x²+2x+1)

x⁴+2x³+x²+2x³+4x²+2x+x²+2x+1

x⁴+4x³+6x²+4x+1

coefficient of x²=6

x is variable or an unknown value to find

example:

2x = 5 which means x = 3
