Question

w isthe factored form of the following?
x2 - x - 42

Answer 1

x^(2)-x-42

For a polynomial of the form x^(2)+bx+c, find two factors of c (-42) that add up to b (-1). In this problem 6*-7=-42 and 6-7=-1, so insert 6 as the right hand term of one factor and -7 as the right-hand term of the other factor.
(x+6)(x-7)

Answer 2

thank you
