Hello yall I'm desperate. Buddy has hit rock bottom. I have a math test coming up and I'm mathematically deficient. I don't know any smart niggas and being a former tutor, I have too much pride to go to my old tutoring business for help. I need one of yall smart asian niggas to help me.

I know I burned some bridges with your race (shoutout to andy "29 inch waist" frailnguyen and Kevin "Ayo Muma" Ma) but I am pleading here because I know yall are the undisputed champions of mathematics. I can't pay yall so if anyone has it in their heart to help a fellow HB nigga out, it would be appreciated. #OYYOY #DESPERATE #DERRICKROSEBRAIN

Solve each equation. Express nonreal solutions in the form a + bi.

2. (x + 3)(x + 5) = 10

The answer to the above equation is: -4 plus or minus the squareroot of 11.

The problem is I have no fucking clue how to get to that answer. I'm stumped. Again if yall could help I appreciate it.

1. (x+3)(x+5) = 10

2. x^2 + 8x + 15 = 10

3. x^2 + 8x + 5 = 0

4. Use the Quadratic equation to solve

Exactly. I tried the quadratic jawn and it didn't get to where I need to be pause.

I plugged the numbers he gave into wolframalpha to check it and they get the answer he posted, but I'm not sure how. I'm not getting them with the quadratic formula.

Wolfram is getting x = - 4 - sqrt11

LMFAO...smfh...i'm a dumb nigga like i said when it comes to math. I thought you had to subtract both sides by -15. SMH though that's the problem. I have no fucking clue how to get to that answer without using some calculator jawn. Thank you for the assitance though yall, buddy appreciates it

Was doing HW and got stuck on this question, might as well ask now that I saw this thread.

1. Jennifer invested a certain amount of money at 14.35% interest rate and $15,000 more than that amount at 17.25% interest rate. Her total yearly interest was $14,355.82.
a) How much did she invest at each rate?
b) What will be her total amount at the end of one year?

so basically with quadratic you got

x= (- 8 +/- sqrt(44) ) / 2

you can break up the sqrt(44)
sqrt(44) = sqrt(4)*sqrt(11)
and sqrt(4) = 2

so then you got

x = (-8 +/- 2*sqrt(11)) / 2
x = -4 +/- sqrt(11)

Is that the exact wording of the problem? I'll try it, but no promises. Been a long time since I've had to do any of this stuff.

Yeah that's exactly how I got it.
Tried using the simple interest formula PTR/100.

(X x 14.35 x 1) / 100 + ((X + 15000) x 17.25) / 100 = 14,355.82

Got X = 372.4
Pretty sure it's wrong

Edit: dunno if i should use a simultaneous eq instead

^ tried to help, realized how much trying to type mathematically sucks... pretty sure if you follow the basic I=PRT formula you should be able to get it.. if not one of these Asians will help you.

37241.5

with the info given that looks about right. i'm not sure though.
I used x(.1435)+((x+15000)(.1725))=14355.82

That's what I did. That's the only way I can think to solve it. I would assume it's right unless all three of us are making the same mistake.

So then part a)
First sum = 37241.5 x 14.35 x 1 / 100
= 5,344.16

Second sum = (37241.5 + 15000) x 17.25 x 1 / 100
= 9,011.6

First sum + second sum = 14,355.76 which is the same amount in the question so that part is right
How do I do part B?

Wouldn't it just be 37241.5 + (37241.5 + 15,000) + 14,355.76 = 103838.76
