Answer:
D) Jack made a mistake while squaring first term, 16x^2 - 8x +1
Step-by-step explanation:
[tex](4x-1)^2[/tex]
we apply (a-b)^2 formula
[tex](a-b)^2 = a^2 - 2ab +b^2[/tex]
a= 4x and b= 1
Replace 'a' with 4x and 'b' with 1
[tex](4x-1)^2 = (4x)^2 - 2(4x)(1) +1^2[/tex]
(4x)^2 is 16x^2
[tex](4x-1)^2 = 16x^2 - 8x +1[/tex]
Jack made a mistake while squaring first term
(4x)^2 is 4^2x^2 that is 16x^2
