Question

For each expression, write an equivalent expression in standard form. Show your reasoning. a.) (2x + 5)(x + 1)

Answer 1

2x² + 7x + 5

Step-by-step explanation

This is a quadratic function, because it has two 'x' multiplying in different terms.

The standard form of a quadratic function is:

`ax^2+bx+c`

To transform this expression in standard form we have to apply the distributive property to multiply the terms in the parenthesis:

So for this expression a = 2, b = 7 and c = 5.
