2. 2(3a-b) = 6a-2b

3. 5(-5x+3) = -25x+15

4. -(2c+3) = -2c-3

Both of their first step are correct (Show your calculations to explain)

Rationalize the denominator of the fraction and enter the new denominator below. 8/2-√12

Studentka2010 [4]

$\frac{8}{2-\sqrt{12}}=\frac{8}{2-\sqrt{4\cdot3}}=\frac{8}{2-2\sqrt3}=\frac{8}{2(1-\sqrt3)}=\frac{4}{1-\sqrt3}\\\\\frac{4}{1-\sqrt3}\cdot\frac{1+\sqrt3}{1+\sqrt3}=\frac{4(1+\sqrt3)}{1^2-(\sqrt3)^2}=\frac{4(1+\sqrt3)}{1-3}=\frac{4(1+\sqrt3)}{-2}=-2(1+\sqrt3)}\\\\=-2-2\sqrt3$

$if\ \frac{8}{2}-\sqrt{12}=4-\sqrt{4\cdot3}=4-2\sqrt3$

I WOULD LIKE THIS SOOVED WITH A BREAK DOWN (5x - 4)2= 36

Neko [114]

$\bf (5x-4)^2=36\implies (5x-4)(5x-4)=36\impliedby using\ FOIL
\\\\\\
5^2x^2-40x+16=36\implies 25x^2-40x+16-36=0
\\\\\\
25x^2-40x-20=0\implies 5(5x^2-8x-4)=0
\\\\\\
5x^2-8x-4=0\implies (5x+2)(x-2)=0\implies 
\begin{cases}
5x+2=0\\
5x=-2\\\\
x=\cfrac{-2}{5}\\
-----\\
x-2=0\\
x=2
\end{cases}$
