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

Expand: 
(5x  1)^{5} 

Section 1: First, substitute values for coefficients, the avalue, and the bvalue. 
(5x  1)^{5} =


Section 2: Next, write the correct final coefficients. 
(5x  1)^{5} = x^{5} + x^{4} + x^{3} + x^{2} + x +
