| ( x + 4 ) ( x - 1 ) - x ^ { 2 } | = 2 ( 2
Solve for x
x=0
x = \frac{8}{3} = 2\frac{2}{3} \approx 2.666666667

|x^{2}+3x-4-x^{2}|=2\times 2
Use the distributive property to multiply x+4 by x-1 and combine like terms.
|3x-4|=2\times 2
Combine x^{2} and -x^{2} to get 0.
|3x-4|=4
Multiply 2 and 2 to get 4.
3x-4=4 3x-4=-4
Use the definition of absolute value.
3x=8 3x=0
Add 4 to both sides of the equation.
x=\frac{8}{3} x=0
Divide both sides by 3.
