Factor the expression shown below completely. 18x^2 -60x +50

Mathematics

For this case we have the following polynomial:
 18x ^ 2 -60x +50

 We do common factor 2:
 2 (9x ^ 2 -30x + 25)

 We now factor the expression into parentheses.
 We have then:
 2 (3x-5) (3x-5)

 Then, rewriting we have:
 2 (3x-5) ^ 2
 Answer:
 
The factored expression is:
 
2 (3x-5) ^ 2

18x² - 60x + 50
= 2 (9x² - 30x + 25 )  ⇒⇒⇒ take 2 as common from all terms
note:  9x² = 3x * 3x   and   25 = 5*5   and   3x * 5 *2 = 30x

so, this is a complete square

= 2(3x-5)(3x-5)
= 2(3x-5)²

The area of a square is given by x?, where x is the length
Rudik [331]

Answer:

Step-by-step explanation:

If she doubles the area of her lot, it should be 2x^2.

But how do you get that?

The answer is that the sides have now increased to √2x

How did I get that, and why did I choose it?

  • The formula for a square's area is s^2
  • If you want to double the area, it will be 2 s^2.  Now what?
  • Take the square root of 2s^2 which is √(2s^2).
  • What that means is the side is now √2 s
