Step-by-step explanation:

(2x^3+6x-1)+(3x^2-7x)

sattari [20]

For this case we must simplify the following expression:

$(2x ^ 3 + 6x-1) + (3x ^ 2-7x)$

We eliminate the parentheses taking into account that:

$+ * + = +\\+ * - = -$

So, we have:

$2x ^ 3 + 6x-1 + 3x ^ 2-7x =$

We add similar terms taking into account that:

Different signs are subtracted and the sign of the major is placed:

$2x ^ 3 + 3x^2-x-1$

Answer:

$2x ^ 3 + 3x^2-x-1$

Simplify the left side of equation so it looks like the right side. cos(x) + sin(x) tan(x) = sec (x)

uranmaximum [27]

Step-by-step explanation:

Consider LHS

$\cos(x) + \sin(x) \tan(x) = \sec(x)$

Apply quotient identies

$\cos(x) + \sin(x) \times \frac{ \sin(x) }{ \cos(x) } = \sec(x)$

Multiply the fraction and sine.

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

Make cos x a fraction with cos x as it denominator.

$\cos(x) \times \cos(x) = \cos {}^{2} (x)$

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

Pythagorean Identity tells us sin squared and cos squared equals 1 so

$\frac{1}{ \cos(x) } = \sec(x)$

Apply reciprocal identity.

$\sec(x) = \sec(x)$
