can you draw it

Answer 2

this question didn't come with a graph ? :o

Answer 3

\[2x^2-2x-4 = 0\]

Answer 4

2x^(2)-2x-4=0

Factor out the GCF of 2 from 2x^(2)-2x-4.
2(x^(2)-x-2)=0

Factor the trinomial x^(2)-x-2.
2(x+1)(x-2)=0

Divide both sides of the equation by 2. Dividing 0 by any non-zero number is 0.
(x+1)(x-2)=0

Set each of the factors of the left-hand side of the equation equal to 0.
x+1=0_x-2=0

Since 1 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 1 from both sides.
x=-1_x-2=0

Set each of the factors of the left-hand side of the equation equal to 0.
x=-1_x-2=0

Since -2 does not contain the variable to solve for, move it to the right-hand side of the equation by adding 2 to both sides.
x=-1_x=2

The complete solution is the set of the individual solutions.
x=-1,2
