Nnesha (nnesha):

is the leading coefficient equal to one ?

OpenStudy (abbey2804):

um... its x squared + 3x -15

Nnesha (nnesha):

what are the factors of 15 ?

OpenStudy (abbey2804):

1 and 15 3 and 5

Nnesha (nnesha):

oaky -1 times 15 = -15 but it's not equal to 3 when you add them -3 times 5 = -15 but you will not get positive 3 so thats mean it's not factorable
