Simply (tan^2 x - sec^2 x)(sin^2 x + cos^2 x)

kati45 [8]

we can use pythagorean identieis

remember that $sin^2(x)+cos^2(x)=1$

also remember that $tan(x)=\frac{sin(x)}{cos{x}}$ and $sec(x)=\frac{1}{cos(x)}$

so if we take $sin^2(x)+cos^2(x)=1$ and divide both sides by $cos^2(x)$ we get

$\frac{sin^2(x)}{cos^2(x)}+\frac{cos^2(x)}{cos^2(x)}=\frac{1}{cos^2(x)}$

$(\frac{sin(x)}{cos(x)})^2+1=(\frac{1}{cos(x)})^2$

$tan^2(x)+1=sec^2(x)$

subtracting $1+sec^2(x)$ from both sides

$tan^2(x)-sec^2(x)=-1$

now subsitute into original problem

$\frac{tan^2(x)-sec^2(x)}{sin^2(x)+cos^2(x)}=$

$\frac{-1}{1}=$

$-1$

the answer is -1

Solve for x.<br>8 + 6x<br>4*+2

zheka24 [161]

Answer:

x = 0

Step-by-step explanation:

8 + 6x = 4 * 2

If this is the equation then start with multiplying 4 by two and subtracting 8 from both sides

6x = 0

Divide 6 from both sides

x = 0

To test this, insert the value of x which is 0

8 + 6(0) = 4 * 2

Multiply 6 and 0

8 + 0 = 4 * 2

Multiply 4 and 2

8 + 0 = 8

Add

8 = 8

This equation is true as you can see so x is equal to 0.

Hope this helps.

What is the product x^2-16 over 2x+8 • x^3-2x^2+x over x^2+3x-4

Oxana [17]

Answer:

$\dfrac{x^3-5x^2 +4x}{2x+8}$

Step-by-step explanation:

The basic idea is to factor each expression and cancel common factors from numerator and denominator.

$\dfrac{x^2-16}{2x+8}\cdot\dfrac{x^3-2x^2 +x}{x^2+3x-4}=\dfrac{(x-4)(x+4)}{2(x+4)}\cdot\dfrac{x(x-1)^2}{(x+4)(x-1)}\\\\=\dfrac{(x-4)x(x-1)}{2(x+4)}\cdot\dfrac{(x+4)(x-1)}{(x+4)(x-1)}\\\\=\boxed{\dfrac{x^3-5x^2 +4x}{2x+8}}$
