Rewrite the following quadratic functions in intercept or factored form. Show your work.

<u>Answer:</u>

y = 5x (x+2)

<u>Step-by-step explanation:</u>

We are given the following the quadratic function and we are to rewrite it in intercept or factored form:

$y = 5x^2 + 10x$

We can factorize the given expression so taking the common factors out of it to get:

$y=5x^2 + 10x$

$y = 5x (x + 2)$

Therefore, the factored form of the given quadratic function is y = 5x (x+2).
