Question

What is the standard form of `y= (x + 2)(x - 6)`?

Answer 1

Standard form is `y=x^2-4x-12`

Explanation:

This is a function of degree `2` i.e. quadratic equation and its standard firm is `y=ax^2+bx+c`. Hence, the standard form for

`y=(x+2)(x-6)` is

= `x(x-6)+2(x-6)`

= `x^2-6x+2x-12`

= `x^2-4x-12`
