The answer is B. Y= (2/3)X - 3
Assuming that the blank space is a plus
2x^2+12x-14=0
isolate x
(2x^2+12x)-14=0
undistribute 2
2(x^2+6x)-14=0
take 1/2 of 6 and square and add negative and positive
2(x^2+6x+9-9)-14=0
factor perfect squrae
2((x+3)^2-9)-14=0
distribute
2(x+3)^2-18-14=0
2(x+3)^2-32=0
2(x+3)^2=32
divide 2
(x+3)^2=16
sqrt
x+3=+/-4
minus 3
x=+/-4-3
x=-7 or 1

Answer:
6n^2 + 5n = 4
Step-by-step explanation:
Represent the number by n. Then: 6n^2 + 5n = 4.
Next time, please include complete instructions. What were you supposed to do here?
Answer:
Parallel I checked with a graph
You can using any equation you want to solve for one of the variables. For instance, if you want to solve for x you turn one of the equations so y is by its self
<span>
2x + 3y = 5
4x - y =3
I am going to use </span>4x - y =3
-y = -4x + 3
y = 4x -3
Now you can substitute 4x - 3 for y in 2x + 3y = 5 and solve for x
2x + 3y = 5
2x + 3(4x - 3) = 5
