On a test, Leo is asked to completely factor the polynomial 3x3 – 3x + 5x2 – 5. He uses double grouping to get (x2 – 1)(3x + 5).

Step2247 [10]

Answer:

Leo does not factored the polynomial completely.

3x^3-3x+5x^2-5=(x+1)(x-1)(3x+5)

Step-by-step explanation:

Given: On a test, Leo is asked to completely factor the polynomial

3x^3-3x+5x^2-5.

also, he uses double grouping to get (x^2- 1)(3x+5)

We have to explain whether he factored the polynomial completely or not.

Consider the given polynomial 3x^3-3x+5x^2-5.

after double grouping he get (x^2- 1)(3x+5)

Also, we can simplify further ,

Using algebraic identity a^2-b^2=(a+b)(a-b)

We get,

(x^2- 1)=(x+1)(x-1)

We get, (x^2- 1)(3x+5)=(x+1)(x-1)(3x+5)

Thus, 3x^3-3x+5x^2-5=(x+1)(x-1)(3x+5)

Thus, He does not factored the polynomial completely.

Can anyone plz help me with these two questions

Answer:

6 and 7

Step-by-step explanation:

6) x^5y^7 / x^2y^3

= x^(5-2) * y^(7-3)

= x^3y^4

7) $\sqrt[3]{300}$

= 6.69432..

OR you can try 6^3 and 7^3 values

216 343

as 300 is between 216 and 343

so \sqrt[3]{300} is between 6 and 7

so it is between 6 and 7
