Question

X-4/x-7√x+10 сократите дробь​

Answer 1

x-7√x+10

D=49-40= 9

√x1= (7+3)/2= 5

√x2= (7-3)/2= 2

$\frac{(\sqrt{x}-2)(\sqrt{x}+2)}{(\sqrt{x}-5)(\sqrt{x}-2)}= \frac{\sqrt{x}+2}{\sqrt{x}-5}$

Answer 2

To simplify the expression, we first need to identify the common factors in the numerator and denominator. However, I assume there might be a typo in your expression. I'll assume you meant:

(x^4 - x)/(√x + 10)

To simplify this expression, we'll factor the numerator and then cancel any common factors with the denominator. Let's go through the steps:

Step 1: Factor the numerator x^4 - x can be factored as x(x^3 - 1).

Step 2: Cancel common factors Now, let's cancel any common factors between the numerator and denominator. We see that both the numerator and the denominator have a factor of (x + 1). So, we can cancel it out:

(x^4 - x)/(√x + 10) = [x(x^3 - 1)] / (x + 1)(√x + 10)

Now the expression is simplified. If you meant a different expression, please clarify, and I'll be happy to help you further!
