a -7,4


b -7, -4


c 3,4


d -3,-4

What is the solution set of the equation x squrad + 11x +28 = 0 a b c or d?
this is an easy quadratic to factor:





(x+7)(x+4)=0


the roots are -4 and -7
Reply:x² + 11x + 28 = 0


(**Factor**) =


(x+7)(x+4) = 0


(x+7) = 0 (x+4)=0


(**subtract the 7 and the 4)


x = -7 x = -4





Solution set: b (-7, -4)














hope that helped!
