For the expression: (− 1/x )× 1−x/1+x × x/x^2−1 Simplify the expression.

Contact [7]

Answer:

The simplified answer is $1/(x+1)^{2}$

Step-by-step explanation:

For the given expression: (− 1/x )× 1−x/1+x × x/x^2−1

we need to simplify it

$x^{2} -1$ = (x+1)×(x-1)

eliminating x and x-1 from the given equation we get

$1/(x+1)^{2}$

The value of x can't be zero

As we can't divide zero by zero

The value of x can't be one

As we can't divide zero by zero

The simplified answer is $1/(x+1)^{2}$

Please show all work: If f(x) = 2x² + x - 3, find x if f(x) = 25.

Katyanochek1 [597]

$f(x) = 2x {}^{2} + x - 3 \\ f(x) = 25 \\ 2x {}^{2} + x - 3 = 25 \\ 2x {}^{2} + x - 28 = 0 \\ \\ x_{1} = \frac{ - 1 + \sqrt[]{1 {}^{2} - 4(2)( - 28) } }{2(2)} \\ x_{1} = \frac{ - 1 + 15 }{4} = \frac{14}{4} = 3.5$

$x_{2} = \frac{ - 1 - \sqrt{225} }{4} = \frac{ - 1 - 15}{4} = \frac{ - 16}{4} = - 4 \\$
