nnesha · Answer

quadratic equation is 
Ax^2 + Bx+C=0
so first move -2 to the left side 
and then use quadratic formula

anonymous · Answer

use the quadratic formula, do you know that?

:)$$\huge\ x = \frac{ -b \pm \sqrt{b^2 -4ac} }{ 2a }$$

nnesha · Answer

okay for that one just find two number
if you multiply them you should get 4 and if you add or subtract them you should get 2

anonymous · Answer

once you plug in - A is the correct answer.  I uploaded the pix also...caught I typed a^2 instead of b^2

anonymous · Answer
