Answer:

2x^2+xy-3y^2

Step-by-step explanation:

Start by taking everything out of the parentheses:

3x^2-2xy-2y^2-x^2-(-3xy)-(y^2)

Note two negatives make a positive:

3x^2-2xy-2y^2-x^2+3xy-y^2

Combine like terms:

3x^2-x^2-2xy+3xy-2y^2-y^2

Simplify

2x^2+xy-3y^2

Which statements about the graph of the function f(x) = 2x2 – x – 6 are true? Check all that apply.
lbvjy [14]
Hello,

1: dom f=R
2: img f =R
3: 2x²-x-6=2(x²-2x/4+1/46)-6-1/8=2(x-1/4)²-49/8
Vertex=(1/4,-49,8)

4: roots are -3/2 and 2
2(x-1/4)²-49/8=1/8[(4x-1)²-49]=1/8*(4x+6)(4x-8)

5:

Sum of two sides of triangle > third side of the triangle  

Case1. When third side is 10

Thee third side can’t be equal to 10 because it does not follow the rule of triangle  

10+10>26………which is  not possible

So the third side of the isosceles triangle is 26.
