x2 + 3x

x = 1.7

8.5

Step-by-step explanation:

Our current equation is:

x2 + 3x.

Let's replace all the x with 1.7.

1.7(2) + 3(1.7)

Let's solve this new equation normally, as if the 1.7 was always there.

1.7(2) = 3.4

3(1.7) = 5.1

Now, let's add both the products.

5.1 + 3.4 = 8.7

Therefore, we can conclude the answer is 8.7.
