Answer:

=−18x^4y−9x^4+27x^2y^2

Step-by-step explanation:

(−9x^2)(x^2+2x^2y−3y^2)

=(−9x^2)(x^2+2x^2y+−3y^2)

=(−9x^2)(x^2)+(−9x^2)(2x^2y)+(−9x^2)(−3y^2)

=−9x^4−18x^4y+27x^2y^2

=−18x^4y−9x^4+27x^2y^2

Hope I helped! Have a great day :)

8x+21=3 need the answer please
GarryVolchara [31]

Answer:

x=-\frac{9}{4}

Step-by-step explanation:

<u>Step 1:  Subtract 21 from both sides</u>

8x + 21 = 3

8x + 21 - 21 = 3 - 21

8x = -18

<u>Step 2:  Divide 8 from both sides</u>

8x = -18

\frac{8x}{8}=-\frac{18}{8}

x=-\frac{9}{4}

Answer:  x=-\frac{9}{4}

Find the sum 3 + (-6)
Gennadij [26K]

To find the sum of two numbers, we must add them together. However, in this case we are adding a negative number. Addition of a negative number can also be written as subtraction, and this method is easier for most people to compute and understand, so we are going to rewrite the expression as follows:

3 - 6

Next, we must just perform the subtraction.

3 - 6 = -3

Therefore, your answer is -3.

Hope this helps!

What is the value of n so that the expression x^2+12X+n is a perfect square trinomial?
Anton [14]
N is equal = 36

Or

n = 6^2

Because,

x^2 + 12x + 36 = x^2 + 2.6x + 6^2

= ( x + 6)^2
