Answer:

Step-by-step explanation:

\sqrt{2z} + 3 = -z

\sqrt{2z} = -z - 3

Square both sides , we have

2z = (-z-3)^{2}

2z = z^{2} + 6z + 9

re arranging the equation , we have

z^{2} + 6z - 2z + 9 = 0

z^{2} + 4z + 9 = 0

This will give a complex roots , solving by quadratic formula

z = -2 + \sqrt{5}i , -2 - \sqrt{5}i

Answer:

<em>If you mean √2z + 3 = -z, the answer is ∅</em>

If you mean √2 z + 3 = -z

√2 z + 3 = -z

√2 z = -z - 3

√2 z + z  = - 3

z(√2 + 1) = -3

z = -3 / (√2 + 1)

z = -3 (√2 - 1)

Find the value of the missing coefficient in the factored form of 27f^3 + 125g^3. 27f^3+125g^3=(3f+5g)(9f^2-?fg + 25g)^2
7nadin3 [17]

Answer:

15

Step-by-step explanation:

The formula for factoring a sum of cubes is:

a^3+b^3=(a+b)(a^2-ab+b^2)

We have a=3f and b=5g here.

So a*b in this case is 3f*5g=15fg.

The ? is 15.
