√(112) - √(80) / √(20) - √(28) = ?

Evgesh-ka [11]

$\large\underline{\sf{Solution-}}$

<u>We need to solve,</u>

$\dfrac{\sqrt{112}-\sqrt{80}}{\sqrt{20}-\sqrt{28}}$

We can write the above mentioned expression as,

$\sf\longmapsto\dfrac{\sqrt{2\times2\times2\times2\times7}-\sqrt{2\times2\times2\times5}}{\sqrt{2\times2\times5}-\sqrt{2\times2\times7}}$

So,

$\sf\longmapsto\dfrac{\sqrt{4\times4\times7}-\sqrt{4\times4\times5}}{\sqrt{2^2\times5}-\sqrt{2^2\times7}}$

So,

$\sf\longmapsto\dfrac{\sqrt{4^2\times7}-\sqrt{4^2\times5}}{\sqrt{2^2\times5}-\sqrt{2^2\times7}}$

Hence,

$\sf\longmapsto\dfrac{4\sqrt{7}-4\sqrt{5}}{2\sqrt{5}-2\sqrt{7}}$

Taking common in respective terms,

$\sf\longmapsto\dfrac{4(\sqrt{7}-\sqrt{5})}{2(\sqrt{5}-\sqrt{7})}$

On cancelling 4 with 2,

$\sf\longmapsto\dfrac{4\!\!\!/^{\:2}(\sqrt{7}-\sqrt{5})}{2\!\!\!/(\sqrt{5}-\sqrt{7})}$

$\sf\longmapsto\dfrac{2(\sqrt{7}-\sqrt{5})}{(\sqrt{5}-\sqrt{7})}$

Taking (-) common,

$\sf\longmapsto\dfrac{-2(\sqrt{5}-\sqrt{7})}{(\sqrt{5}-\sqrt{7})}$

So, (√5 - √7) gets cut,

<u>Hence, </u>

$\longmapsto\bf\dfrac{\sqrt{112}-\sqrt{80}}{\sqrt{20}-\sqrt{28}}=-2$

Find the value or values of the Y in the quadratic equation y squared + 4 y + 4 equals 7

QveST [7]

Y² + 4y + 4 = 7
   - 7 - 7
y² + 4y - 3 = 0
   y = -(4) ± √((4)² - 4(1)(-3))
   2(1)
   y = -4 ± √(16 + 12)
   2
   y = -4 ± √(28)
      2
   y = -4 ± 2√(7)
      2
   y = -2 ± √(7)
   y = -2 + √(7) U y = -2 - √(7)

Бу +11 = 17<br> бу =<br> y =

Feliz [49]

Answer:

y=1

Step-by-step explanation:

Original Equation:

6y+11=17(<em>Group</em><em> </em><em>like</em><em> </em><em>terms</em>)

6y=17-11(<em>You </em><em>will </em><em>subtract</em><em> </em><em>1</em><em>1</em><em> </em><em>from</em><em> </em><em>1</em><em>7</em><em>)</em>

<em>6</em><em>y</em><em>=</em><em>6</em><em>(</em><em>You</em><em> </em><em>will</em><em> </em><em>then</em><em> </em><em>Divide</em><em> </em><em>Both </em><em>Sides </em><em>by</em><em> </em><em>6</em><em>)</em>

<em>Y</em><em>=</em><em>1</em><em>(</em><em> </em><em>Leaving</em><em> </em><em>y</em><em> </em><em>with</em><em> </em><em>1</em><em> </em><em>because </em><em>6</em><em> </em><em>will</em><em> </em><em>cancel</em><em> </em><em>each</em><em> </em><em>other </em><em>out</em><em>,</em><em> </em><em>and</em><em> </em><em>6</em><em> </em><em>divided </em><em>by</em><em> </em><em>6</em><em> </em><em>is</em><em> </em><em>1</em><em>)</em>
