Quadratic equations are the equations that can be re arranged in the linear or the standard form.

<u>Explanation:</u>

In algebra, a quadratic equation is any condition that can be adjusted in standard structure as where x speaks to an unknown, and a, b, and c speak to known numbers, where a ≠ 0. On the off chance that a = 0, at that point the condition is straight, not quadratic, as there is no term.

Quadratic equations are really utilized in regular day to day existence, as while ascertaining regions, deciding an item's benefit or figuring the speed of an article. Quadratic conditions allude to conditions with in any event one squared variable, with the most standard structure being ax² + bx + c = 0.

Solve for x. <br> 2(x-2)= 6x + 2 -2(-2x - 4)
Lena [83]

Answer:-7/4

Step-by-step explanation:

2(x-2)=6x+2-2(-2x-4)

Open brackets

2x-4=6x+2+4x+8

Collect like terms

-4-2-8=6x+4x-2x

-14=8x

Divide both sides by 8

-14/8=8x/8

-7/4=x

x=-7/4

I am lost on what to do
Neko [114]
\bf sin({{ \alpha}})sin({{ \beta}})=\cfrac{1}{2}[cos({{ \alpha}}-{{ \beta}})\quad -\quad cos({{ \alpha}}+{{ \beta}})]&#10;\\\\\\&#10;cot(\theta)=\cfrac{cos(\theta)}{sin(\theta)}\\\\&#10;-----------------------------\\\\&#10;\lim\limits_{x\to 0}\ \cfrac{sin(11x)}{cot(5x)}\\\\&#10;-----------------------------\\\\&#10;\cfrac{sin(11x)}{\frac{cos(5x)}{sin(5x)}}\implies \cfrac{sin(11x)}{1}\cdot \cfrac{sin(5x)}{cos(5x)}\implies \cfrac{sin(11x)sin(5x)}{cos(5x)}

\bf \cfrac{\frac{cos(11x-5x)-cos(11x+5x)}{2}}{cos(5x)}\implies \cfrac{\frac{cos(6x)-cos(16x)}{2}}{cos(5x)}&#10;\\\\\\&#10;\cfrac{cos(6x)-cos(16x)}{2}\cdot \cfrac{1}{cos(5x)}\implies \cfrac{cos(6x)-cos(16x)}{2cos(5x)}&#10;\\\\\\&#10;\lim\limits_{x\to 0}\ \cfrac{cos(6x)-cos(16x)}{2cos(5x)}\implies \cfrac{1-1}{2\cdot 1}\implies \cfrac{0}{2}\implies 0
