Question
Describe the error in factoring the polynomial of x^9+8x^3 and correct the error given in the photo and correct it and solve the equation
x° + 8x = (x)3 + (2x)
= (x³ + 2x)[(x®)2 (x³)(2x) + (2x)²]
= (x³ + 2x)(x6 – 2xt + 4x)
%3D
O The sum of cubes factoring pattern is not applied correctly.
O The term 8x is not written correctly as a perfect cube in the first line.
O The polynomial is not completely factored.
O The term
(x) is not simplified correctly in the third line.
