Given: 
(a + b)^{6} = _{6}C_{0}a^{6} + _{6}C_{1}a^{5}b + _{6}C_{2}a^{4}b^{2} + _{6}C_{3}a^{3}b^{3} + _{6}C_{4}a^{2}b^{4} + _{6}C_{5}ab^{5} + _{6}C_{6}b^{6} 

Expand: 
(2x + 4)^{6} 

Section 1: First, substitute values for coefficients, the avalue, and the bvalue. 
(2x + 4)^{6} =


Section 2: Next, write the correct final coefficients. 
(2x + 4)^{6} = x^{6} + x^{5} + x^{4} + x^{3} + x^{2} + x +
