Question

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

x2 + x - 12 = 0

Answer 1

notice that x = 4x -3x
use that fact to factor the equation

Answer 2

\[-b \pm \sqrt{b^2-4ac}\]----------------\[2a\]\[-1\pm \sqrt{1^2-4*1*-12}\]---------------------\[2*1\]\[-1\pm \sqrt{1+12}\]--------------\[2\]

Answer 3

@mathfrick 4*12 = 48
you made a slight mistake there.

Answer 4

try factoring as
\[(x+4)(x-3)=0\]

Answer 5

\[-b \pm \sqrt{1+48}\]------\[2\]
