Answer: Factoring 3x2-2x-7
The first term is, 3x2 its coefficient is 3 .
The middle term is, -2x its coefficient is -2 .
The last term, "the constant", is -7
Step-1 : Multiply the coefficient of the first term by the constant 3 • -7 = -21
Step-2 : Find two factors of -21 whose sum equals the coefficient of the middle term, which is -2 .
-21 + 1 = -20
-7 + 3 = -4
-3 + 7 = 4
-1 + 21 = 20
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
