Solve the Math problem given by the user above you and offer your own.
Creativity is encouraged.
I'll start off simple.

4 x 4 : 23 =

 

[The Pink Panther]

16:8 = 2:1

Find the value of x:

9x^2 + 17x + 46 = 12

 

[Maskull]

Math is gay.

I feel like I’ve been using this clip a lot, but it is relevant.

 

[Monika H.]

16:8 = 2:1

Find the value of x:

9x^2 + 17x + 46 = 12

Equation got no solution. The discriminant is less than 0.

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

I used to be good at math but I forgot so much of it

So you don't know how to solve this? You need some repetition?

 

[The Pink Panther]

Equation got no solution. The discriminant is less than 0.

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

x = 9/5?

 

[Monika H.]

x = 9/5?

Nope

 

[Gentleman Gamer]

I always sucked at math and could never catch onto it for some reason.

 

[The Pink Panther]

Nope

It's not?

I did the problem again, and it is. This is the fraction 9/5 btw. Are you sure?

Math is actually one of the funniest subjects once you get the hang of it.

Say F whoever wants the solution

9x^2 + 17x + 46 = 12

x1/2 = 0.94 +/- 1.69i (rounded to nice)

Show or disprove the following:
FOR ALL x (EXISTS y (-Q(x, (f(y)) AND (P(x) -> EXISTS y R(y)) AND P(x)) <=> FORALL x EXISTS y ((-Q(x, f(y)) AND R(y)) AND P(x))

Well I tried although school and never caught on. Now school is over for me and I pretty much forgot everything outside of basic baby math.

It's not.
The method is thus
(x - 1)2 + 2x + 3(x - 1) = (x + 2)2
x2 - 2x + 1 + 2x + 3x - 3 = x2 + 4x + 4
x2 - x2 - 2x + 2x + 3x - 4x = 3 - 1 + 4
- x = 6

if you give me one minute I'll even do the verification.

 

[Monika H.]

Verification
(x - 1)2 + 2x + 3(x - 1) = (x + 2)2
(-6 - 1)2 + 2·(-6) + 3·(-6 - 1) = (-6 + 2)2
(-7)2 - 12 + 3·(-7) = (-4)2
49 -12 -21 = 16
16 = 16

x1/2 = 0.94 +/- 1.69i (rounded to nice)

So the equation is impossible.

FOR ALL x (EXISTS y (-Q(x, (f(y)) AND (P(x) -> EXISTS y R(y)) AND P(x)) <=> FORALL x EXISTS y ((-Q(x, f(y)) AND R(y)) AND P(x))

This one's thoug. I gotta write it down and think on it.

So the equation is impossible.

No one specified it had to be in real space.

x = 9/5?

I agree with the machines.

E: fuck you for making me do math.
