(p^{2}-9)(p^{2}+9) = p^4+9p^{2}-9p^{2}-81 = p^{4}-81

The left side of the equation is what you get if you apply the "foil" method to the middle. This is the first step. Now the left-hand side is only partially factored, because you can still factor one of the remaining terms. Notice that one of the terms on the left has a similar form to that of the original question p^4-81. You can apply the same method I did to that term and then you will have fully factored p^4-81. You should have 3 factors in the end. Hope this helps!

Help pls and tysm because I'm not strong in this area. ​

Alright, first thing's first, simplify the equation as much as you can. If you wanted, I suppose you could just multiply everything by 40, but that's super unconventional.

7x/8 - 3x/8 = 1/5 + 3/10

Simplify:
4x/8 = 1/5 + 3/10

Make sure that when subtracting or adding fractions that the denominators (The number on the bottom of the fraction) are equal.

In order to add 1/5 and 3/10 together, all we have to do is ensure that both denominators are equal.

To do this, simply multiply 1/5 by 2/2. The new fraction will be 2/10 (You can do this since it's the exact same fraction, 2/10 will simplify down to 1/5. The reason we did this was to make sure that the two fractions had equal denominators).

Our equation now looks like this:
4x/8 = 2/10 + 3/10

Add the fractions on the right:
4x/8 = 5/10

Huh, whaddya know? Both the fraction on the left and the right can be simplified into 1/2! (4/8 becomes 1/2, and 5/10 becomes 1/2)

1x/2 = 1/2
x/2 = 1/2

If you want to, I suppose you could cross multiply to check, but the answer's already pretty obvious.

x = 1

Good luck! If you need me to explain anything I did here, just ask :))

Y=-3x + 6
slamgirl [31]

Answer:

(-1, 9)    (he x value is placed first).

Step-by-step explanation:

y = -3x + 6

y = 9

Substitute y = 9 into the first equation:

9 = -3(x) + 6

-3x = 9 - 6

-3x = 3

x = -1.
