$\sin(\pi+x) = -\sin(x) \\ \\ 
\sin(\pi-x) = \sin(x) \\ \\ 
\sin(\pi+x) + \sin(\pi-x) = -\sin(x) + \sin(x) = \boxed{0}$

What is the factored form of 3x + 21x-24?

anastassius [24]

Answer:

factorize form of the equation is $24(x-1)=0$ , where $x=1$

Step-by-step explanation:

Given Equation:

$3x + 21x-24=0$

Adding the terms of 'x' and taking constants on the other side.

$24x-24=0$

The sign of the constant will change on changing the side of it.

$24x=24$

$x=\frac{24}{24}$

$x=1$

So, the value of 'x' is 1

The factorized form of the equation can be made by taking the common value from the equation i.e

$24x-24=0\\$

$24(x-1)=0$
