I think... J because
x + 1 / x^3 - x
Factor out x from the expression
x + 1 / xx(x^2 - 1)
Use a^2 - b^2 = (a - b)(a + b) to factor the expression
x + 1 / x • (x - 1) • (x + 1)
Reduce the fraction with x+ 1
1 / x • (x - 1)
Distribute x through the parentheses
1 / x^2 - x
:)
Answer:
= 0
Step-by-step explanation:
-3 = x^2 + 4x + 1
0 = x^2 + 4x + 4
a = 1
b = 4
c = 4
plug the numbers into the equation to find the discriminant value...
4^2 - 4(1)(4)
16 - 16 = 0
therefore your answer is 0
