icang [17]

Answer:

$\boxed {y =3 {x}^{2} + 8x + 15}$

Step-by-step explanation:

$y = 3(x + 3)(x + 5)$

Expand/Distribute x+3 in x+5

$y = 3( {x}^{2} + 8x + 15)$

Distribute 3 in the expression.

$y = 3 {x}^{2} + 24x + 45$

I have a homework about subtracting Integers and i don't get what -9 - 5, 31 - 48, ang -6 - 7 is

Alexxandr [17]

Well remember this:
When the signs are the same it is positive
When the signs are different make it negative

When you are subtracting a negative and positive, it is going to be like adding
for example:
-9 - 5 = -14
You just add 9 and 5 to get 14, the signs are different so it is going to be negative. ONLY WHEN YOU ARE SUBTRACTING NEGATIVES
