Question

what are the factors of the following trinomial ? 2x^2 -7x+ 3

Answer 1

ax^2+bx+c
find two factors of a*c that multiply to be a*c add up to be b
so we have
a*c=2*3=-6(-1)
and
-6-1=-7
we replace -7x with -6x-1x

so we have
2x^2-6x-1x+3
now factor by grouping
2x(x-3)-1(x-3)
(x-3)(2x-1)

Answer 2

soo the answer ( 2x-1) ( x+3)

Answer 3

no (x-3)(2x-1) or since multiplication is commutative (2x-1)(x-3)
