Use the quadratic formula to solve the equation.
x^2 + 11x - 12 = 9

What is the answer?

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}

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

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

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

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.

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