64 POINT QUESTION<br><br> √(5-2x) - √(2-x) = 1

Ivanshal [37]

Answer:

x = 2 and x = -2

Step-by-step explanation:

The easiest way is to guess. We know that you can't have a square root of a negative number. This constrains x between negative infinity to 2. Testing 2 and -2, we see that it satisfy the equation.

The more systematic approach is shown below

$\sqrt{5-2x}-\sqrt{2-x}=1 \\\sqrt{5-2x}-\sqrt{2-x}+\sqrt{2-x}=1+\sqrt{2-x} \\\sqrt{5-2x} = 1+\sqrt{2-x}$

$5-2x=(1+\sqrt{2-x})^2\\5-2x=1+2\sqrt{2-x}+2-x\\2-x=2\sqrt{2-x}\\1-0.5x=\sqrt{2-x}\\(1-0.5x)^2=2-x\\1-x+0.25x^2=2-x\\0.25x^2-1=0\\0.25x^2 = 1\\x^2 = 4\\x = +/-2$

x= -2, 2

Plsss help this is due today

It’s 20cm :) because knowing that you have a 3:5 ratio and that one side is 12 can you can make a ration table so 3:5 and 12:? And to get from 3 to 12 you have to multiply 3 by 4 so you have to do the same to the other side 5 times 4 is 20 so 20 cm

Option B gives the correct answer.

The step by step solution using the FOIL method of multiplication is given below:

$(8 x^{5}+9)(8 x^{3}+9) \\ \\ 
 =8 x^{5} (8 x^{3}+9) +9(8 x^{3}+9) \\ \\ 
=64 x^{8} +72 x^{5}+72 x^{3}+81$
