Question

Which of the following are the factors of a^2+ab+bc+ca ?​

Answer 1

I guess this is your answer but this question is wrong I don't know but your answer is ready answer

Answer 2

${a}^{2} + ab + bc + ac$

Rearranging the terms,

$= {a}^{2} + ab + bc + ac$

$= a(a + c) + b(a + c)$

$= (a + b)(a + c)$
