# What is the standard form of y= (x - 8) (x+6) ?

Jun 27, 2016

$y = {x}^{2} - 2 x - 48$

#### Explanation:

It is a quadratic function and standard form of quadratic function is

$y = a {x}^{2} + b x + c$

To convert, let us multiply the RHS as follows:

$y = \left(x - 8\right) \left(x + 6\right)$

= $x \left(x + 6\right) - 8 \left(x + 6\right)$

= ${x}^{2} + 6 x - 8 x - 48$

= ${x}^{2} - 2 x - 48$
