Hey there!

3x(x - 2) + 7x - 1

DISTRIBUTE 3x WITHIN the PARENTHESES

= 3x(x) + 3x(-2) + 7x - 1

= 3x^2 - 6x + 7x - 1

COMBINE the LIKE TERMS

= (3x^2) - 6x + 7x - 1

= 3x^2 + 1x - 1

= 3x^2 + x - 1

Therefore, your answer is: “3x^2 + x - 1” OR you could say “3x^2 + 1x - 1” because they are both equivalent to each other

Good luck on your assignment and enjoy your day!

Can somebody explain step by step ?
lukranit [14]

Answer:

3m\sqrt[5]{2m^4p^4}

Step-by-step explanation:

We want to find the fifth root of 486m^9p^4. In order to do so, we need to factorise

Let's factorise 486 first:

486 = 2 * 243 = 2 * 3^5

Ah, we see that 3^5 can be taken out and becomes 3 outside of the 5th root since the 5th root of

Now look at the variables. We see that since we have p^"4", whose exponent is less than 5, it's impossible for us to write it as a power of 5, so we leave this in the root.

We also have m^"9", which can be written as m^"5" * m^"4". Again, we see that the m^"4" term will have to remain inside the root, but we can take out the m^"5", which becomes m.

Our final answer is thus: 3m\sqrt[5]{2m^4p^4}.
