Expanding and Simplifying (x+3)(x+4) to Standard Form
In mathematics, standard form refers to a specific way of writing a polynomial expression. For a quadratic expression, the standard form is ax² + bx + c, where 'a', 'b', and 'c' are constants.
Let's expand and simplify the expression (x+3)(x+4) to achieve its standard form:
Expanding the Expression
We can use the FOIL method (First, Outer, Inner, Last) to expand the product:
- First: x * x = x²
- Outer: x * 4 = 4x
- Inner: 3 * x = 3x
- Last: 3 * 4 = 12
Combining these terms, we get: x² + 4x + 3x + 12
Simplifying to Standard Form
Now, we can combine the like terms (4x and 3x) to achieve the standard form:
x² + 7x + 12
Therefore, the standard form of the expression (x+3)(x+4) is x² + 7x + 12.
