For the equation y= 6x2 - 9x + 22, choose the correct application of the quadratic formula.

The  correct application of the quadratic formula is:

The quadratic equation is given by:

We know that the solution of the quadratic equation:

is given by:

Here we have:

and

Hence, the quadratic formula is given by:

i.e.

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form
