`y = (2x + 7)(x + 4)` Write the quadratic function in standard form.
The standard from is `Ax^2 + Bx + C`
Use First Outer Inner Last (FOIL) to remember how to expand the polynomial.
(2x + 7)(x + 4)
`(2x^2 + 15x + 28)` is the quadratic in standard form.
When we multiply`2x+7`
We get `2x^2+7x+8x+28`
Which in simpler form is `2x^2+15x+28`
When we shift 'y' to the other side the equation looks like
There is your quadratic equation
Where a=2, b=15,c=(28-y)
