Answer:
Step-by-step explanation:
[NOTE]
I am assuming x2 is 
, if I am wrong about that then please notify me in the comments
[END NOTE]
The parenthesis are implications that we multiply the numbers within them.
Therefore, multiply.
(2x)(x2)
(2x)(x)
(2x)(-2)
-4x
(3)(x2)
(3)(x)
3x
(3)(-2)
-6
Now combine like terms, meaning the numbers with the same endings, you cannot add a number with different exponents and adding numbers with and without a variable.

Step-by-step explanation:
the roots are 2
Answer:
(x-4)(x+5) or x^2+x-20
Step-by-step explanation:
If a root of the function is 4, (meaning that when y=0, x=4) it can be rewritten as x-4.
The same goes for if a root is -5. it will simplify to x+5.
These are called factors of a quadratic equation.
Put together, they look like (x-4)(x+5). Using the FOIL method, that can be simplified to x^2+x-20
Answer:
y = - 6
Step-by-step explanation:
Locate x = - 3 0n the x- axis, then go vertically down until the line is met. At this point read the value of y from the y0 axis, that is
When x = - 3, y = - 6
