**Step-by-step explanation:**

<em>Common term of 5.</em>

<em>5(6x²-x-2)</em>

<em>Factor.</em>

<em>6x²-x-2</em>

<em>(6x²+3x)+(-4x-2)</em>

<em>=3x(2x+1)-2(2x+1)</em>

<em>(2x+1)(3x-2)</em>

If you want to do it by hand, you can write the equation

.. y = ax^2 +bx +c

and substitute three of the given points. Then solve the resulting three linear equations for a, b, and c.

.. 4 = a +b +c

.. 7 = 4a +2b +c

.. 12 = 9a +3b +c

Subtracting the first equation from the other two reduces this to

.. 3 = 3a +b

.. 8 = 8a +2b

The latter can be divided by 2, so reduces to

.. 4 = 4a +b

Subtracting the first of the reduced equations from this, you have

.. 1 = a

so

.. 3 = 3*1 +b

.. 0 = b

and

.. 4 = a + b + c = 1 + 0 + c

.. 3 = c

And your equation is

.. y = x^2 +3 . . . . . . as shown previously
