Answer:
Step-by-step explanation:
Draw a horiz. line. Locate x = -7 on this line. It will be 7 units to the left of the origin. Now draw a vertical, dashed line thru x = -7. Shade the area to the right of this dashed line. The shaded area represents the solution set of x > -7.
Answer:3,-3
Step-by-step explanation:
difference of 2 squares
(x+3)(x-3)
x+3=0
x-3=0
x=3,-3
The answer is either
or 
To solve: Let's solve your equation step-by-step.
5x2+5x−x2−x=2004
Step 1: Simplify both sides of the equation.
4x2+4x=2004
Step 2: Subtract 2004 from both sides.
4x2+4x−2004=2004−2004
4x2+4x−2004=0
Step 3: Use quadratic formula with a=4, b=4, c=-2004.
x=
−b±√b2−4ac
/2a
x=
−4±√32080
/8
