Answer and Step-by-step explanation:

Plug in the values 6 and -4 for x and y respectively.

10 + 5(6)(-4)

Multiply 5 and 6 to get 30.

10 + 30(-4)

Multiply 30 and -4 to get -120

10 - 120

Subtract 120 from 10 to get -110.

-110

The value of the expression is -110.

$\bold{Given : 2^2^x^-^2 - 2^x^-^1 = 2^x - 2}$

$\bold{\implies (2^2^x) (2^-^2) - (2^x)(2^-^1) = 2^x - 2}$

$\bold{\implies \frac{(2^2^x)}{(2^2)} - \frac{(2^x)}{(2^1)} = 2^x - 2}$

$\bold{\implies \frac{(2^2^x)}{4} - \frac{(2^x)}{2} = 2^x - 2}$

$\bold{\implies \frac{[2^2^x - (2^x)(2)]}{4} = 2^x - 2}$

$\bold{\implies [2^2^x - (2^x)(2)] = (4)(2^x) - 8}$

$\bold{\implies 2^2^x - (2^x)(2) - (4)(2^x) + 8 = 0}$

$\bold{\implies (2^x)^2 - (2^x)(6) + 8 = 0}$

$\bold{Let\;us\;take : (2^x) = Z}$

$\bold{\implies Z^2 - 6Z + 8 = 0}$

$\bold{\implies Z^2 - 4Z - 2Z + 8 = 0}$

$\bold{\implies Z(Z - 4) - 2(Z - 4) = 0}$

$\bold{\implies Z = 4\;\;(or)\;\;Z = 2}$

$\bold{But : Z = 2^x}$

$\bold{\implies 2^x = 4\;\; (or) \;\; 2^x = 2}$

$\bold{\implies 2^x = 2^2\;\; (or) \;\; 2^x = 2^1}$

$\bold{\implies x = 2\;\;(or)\;\; x = 1}$

The rational expressionwrite this ratio in the form p(x) + x/(x - 2) Where is some x - 2

loris [4]

Answer:

$\frac{2x^2+5x-14}{x-2}=(2x+9)+\frac{4}{x-2}$

Step-by-step explanation:

Given rational expression is,

$\frac{2x^2+5x-14}{x-2}$

x - 2) 2x² + 5x - 14(2x + 9

2x² - 4x

9x - 14

9x - 18

Therefore, $\frac{2x^2+5x-14}{x-2}=(2x+9)+\frac{4}{x-2}$ is the answer.
