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

6

Step-by-step explanation:

Expand (x + 1)⁴:

(x + 1)⁴ = ((x + 1)(x + 1))² =(x² + 2x + 1)² = (x² + 2x + 1)(x² + 2x + 1) =x²(x²) + x²(2x) + x²(1) + 2x(x²) + 2x(2x) + 2x(1) + 1(x²) + 1(2x) + 1(1) = x⁴ + 2x³ + 2x² + 2x³ + 4x² + 4x + 1 = x⁴ + 4x³ + 6x² + 4x + 1

The coefficient of x² is 6

Your maths is very weak try yourself this would improve your skills don't depend on others

Idrk but i think u should figure out the n dia n then the units it will make it way more easier
