Question

HELP, WILL REWARD!!
Use the quadratic formula to solve the equation.

-x^2+5x=11

a.5/2 +- sqrt13/2
b.-5/2 +- sqrt13/2
c.2/5 +- sqrt13/2
d.-2/5 +- sqrt13/2

Answer 1

-x^2+5x-11=0, so i only rewrote the equation right? then you use\[\frac{ -b \pm \sqrt{b ^{2}-4ac} }{ 2a }\]

Answer 2

so put in you a b and c values, a= -1, b=5, c=-11

Answer 3

Okay.

Answer 4

This is how I remember the quadratic formula bro: A negative boy couldn't decide whether to go to a radical party. He was square so he missed out on four awesome chicks. The party was over 2 a.m. Cheers

Answer 5

i still dont get it?

Answer 6

were u hear that at thats how i rember it to

Answer 7

you will now: ax^2+bx+c=0 remember standard form? yea now substitute the values and look for sign changes and stuff and you should be solid :) CHeers
