(1+tan²x)/(tan²x) =

1/tan²x + tan²x/tan²x =

cos²x/sin²x + 1 =

cos²x/sin²x + sin²x/sin²x =

(cos²x + sin²x) / sin²x =

1/sin²x =

csc²x.

Answer:

sin^2(x)-sin(x)=0

Step-by-step explanation:

(1+tan^2(x))/(tan^2(x)) = csc^2(x)

(I don't want to type out how every step looks because it would take a year but i listed every step I used)

Determine the defined range

Transform the expressions

Apply the exponents

Write all numerators above the common denominator

Simplify the expressions

1/(sin^2(x))=1(sin(x))

set the denominators equal

sin^2(x)=sin(x)

move epression to the left

sin^2(x)-sin(x)=0

$=\dfrac{1}{x+2}\cdot\dfrac{x-5}{x-5}+\dfrac{6}{x-5}\cdot\dfrac{x+2}{x+2}\\\\=\dfrac{1(x-5)+6(x+2)}{(x+2)(x-5)}\\\\=\dfrac{7x+7}{x^{2}-3x-10}$

Usually, the "simplified" form has the polynomial multiplied out (as immediately above), rather than factored. If you want it factored, you can remove a factor of 7 from the terms of the numerator to get 7(x+1)/((x+2)(x-5)).

Is x = -3 a solution to the equation -3X^2=-27

Softa [21]

Yes it is.

-3(-3)^2 = -27

-3(9) = -27

-27 = -27
