# What is the standard form of # y= (x + 3)(x + 4) #?

##### 1 Answer

#### Explanation:

A polynomial is in standard form if it is written with all the

It's typically written as

#y=ax^2+bx+c#

where

Standard form is useful because it generalizes how to find the roots of any quadratic equation through the quadratic formula (

In your case, to find the standard version of the equation, distribute the two binomials through the " **FOIL** " method.

**FOIL** stands for **F** irst, **O** uter, **I** nner, **L** ast. These are the four different combinations of terms you can multiply when you have two binomials.

**First**: multiply the first term in each binomial

**Outer**: multiply the terms on the outside

**Inner**: multiply the terms on the inside

**Last**: multiply the last term in each binomial

Now, add all the different products.

Combine like terms.

This is in the standard form of the quadratic equation
