#15x^2-17x+2 = (x-1)(15x-2)#

Explanation:

Given:

#15x^2-17x+2#

Note that the sum of the coefficients is zero.

That is:

#15-17+2 = 0#

So we can deduce that #x=1# is a zero and #(x-1)# a factor.

In order to get the leading term #15x^2# and the constant term #2#, the other linear factor must be #(15x-2)#

So we have:

#15x^2-17x+2 = (x-1)(15x-2)#
