3x^2 + 3x - 6
First factor out the 3 in front of x^2:
3( x^2 + x - 2 )
Now we can look at the inside of the brackets, and find two numbers that, when multiplied, give -2, and when added, give +1. You will usually find them if you create a list of factors of the constant term (-2 in this case).
2 * -1 = -2
2 + -1 = 1
So the factorization becomes 3(x+2)(x-1)

I can help you in spanish

Step-by-step explanation:
Solving the following system of equations:

Let

Putting value of x^2 in eq(2)

Now, finding value of x
Putting y=-5

y=-5, x= 2i and y=-5 , x= -2i
Since we need to find x and y coordinates and its value cannot be in terms of i so we will not consider these as answer
Putting y=3

So,
