#1

Use the quadratic formula to solve the equation.

x^2 + 11x - 12 = 9

What is the answer?

x^2 + 11x - 12 = 9

What is the answer?

#2

x^2+11x-21=0

Then put it into the formula. Which takes ages to write out, so I won't. You should know the formula, just number crunch it.

Possible answers...

{-6, 1}

{-10, 2}

{-3/2, 1}

{-12, 1}

{-6, 1}

{-10, 2}

{-3/2, 1}

{-12, 1}

#4

Plugging things into a formula is the easiest thing in maths ever. Do your homework yourself.

#5

What is the answer?

Errr... ....9?

#6

x^2+11x-21=0

x= -11/2 + V(11/2)^2+21 v x= 11/2 - V(11/2)^2+21

x= 5,5 + V30,25+21 v x= 5,5 - V30,25+21

x=5,5 + 7,16 v x= 5,5 - 7,16

i dunno

x= -11/2 + V(11/2)^2+21 v x= 11/2 - V(11/2)^2+21

x= 5,5 + V30,25+21 v x= 5,5 - V30,25+21

x=5,5 + 7,16 v x= 5,5 - 7,16

i dunno

#7

(x+12)(x-1)=0

x=-12 V x=1

Thankyou sir. You just won me 10 dollars =D

#8

Try paying attention or reading your book. Quadratics are one of the easier things to do in that class.

#9

Thankyou sir. You just won me 10 dollars =D

haha, didn't see the 9 xd

#10

Possible answers...

{-6, 1}

{-10, 2}

{-3/2, 1}

{-12, 1}

Jesus Christ man, you're even given the answers. Just do it yourself. It's basically the easiest thing ever.

#11

Errr... ....9?

This,.

#12

Don't forget the quadratic formula, which makes stuff like that a piece of cake.

#13

I should probably explain the situation.

Ive been out of Highschool for awhile now, and my brother (who is a sophmore) bet me 10 dollars I could not complete his homework. That was the last problem and I was to lazy to figure it out so I asked my friends here in the pit.

#14

the pit should not be doing your homework

#15

let alone your little brother's homework

#16

What is all this stuff? I have been away from school to long and have killed too many brain cells since then

Some sort of blasphemy called Algebra.

Real math begins with Calculus

Oh, I despised Algebra.. so I never paid attention. I never did calculus. Just algebra and geometry.

#19

even i can solve that. and i suck at math. I belive you can even use the vietto rule (dunno how its named in english)
