Question

Is it possible to factor `y=3x^2-10x-14`? If so, what are the factors?

Answer 1

No

Explanation:

Standard form of equation `y = ax^2 + bx + c`

`y = 3x^2 - 10x - 14`

`ac = 3 * -14 = - 42 = - 3 * 7 * 2`

`-14 + 3 = -11, -7 + 6 = -1, -21 + 2 = -19`

As combination factors do not add upto-10, it’s not possible to find the factors.
