Question

Factor completely: −7x^2 + 14x − 21

Answer 1

start by factoring out the common factor of -7

Answer 2

get
\[-7(x^2-2x+3)\] then it will be easier to factor what is inside the parentheses. try it

Answer 3

I think there must a sign error in the expression SaFaree has written down, because

x^2 - 2x + 3

doesn't have nice factorization.

SaF -- check the question and let us know if it is correct.
