What the answer when you factor this polynomial expression.
3x2 + 30x + 75

To factorize a polynomial implies that, we want to get several algebraic expressions from the polynomial.

When is factored, the result is:

Given

Factor out 3

Expand the bracket

Factorize

Factor out x + 5

So, we have:

Hence, the factors of are 3 and (x + 5)

3(x + 5)(x+ 5)  

Step-by-step explanation:

3x² + 30x + 75

Here's one way to do it.

Step 1. Factor out the highest common factor of all three terms.

You can factor out a 3.

3(x² +10x +25) = 0

Step 2. Factor the remaining polynomial

We must find two numbers whose product is 25 and whose sum is 10.

A little trial-and-error gives us 5 and 5.  

5 × 5 = 25; 5 + 5 = 10

We can factor the expression as

3(x + 5)(x + 5)
