Question

Write the quadratic equation in factored form. Be sure to write the entire equation.

x2 + x - 12 = 0

Answer 1

Quadratic formula : -[b+-sqrt { (b^2) - 4ac }] / 2a
Replacing values, we get
-[1+-(1-4(12))] / 2
  =-(1+-(1-48)) /2
  =-(1+-(-47)) /2
So we get two equations:

a= -(1-47)/2
  =-(-46)/2
  = 46/2
  =32

b= -(1+47)/2
  =-48/2
  =-24
