Question

(1) (x + 2)^4 expand by binomial theorem​

Answer 1

Hey friend,

Here is the solution :-

$(a + b)^{4} = {a}^{4} + 4 {a}^{3} b + 6 {a}^{2} {b}^{2} + 4ab^{3} + {b}^{4} \\ \\ here \: a = x \: \: \: \: b = 2 \\ \\ {x}^{4} + 4 {x}^{3} (2) + {6x}^{2} ( {2}^{2} ) + 4x( {2}^{3} ) + {2}^{4} \\ \\ {x}^{4} + {4x}^{3} (2) + {6x}^{2} (4) + 4x(8) + 16 \\ \\ {x}^{4} + {8x}^{3} + {24x}^{2} + 32x + 16$

✨I hope this will help you....✨
