Solve

 $4r^2-100=0$  

• r = 0    or      r = -5

• r = -5   or     r = 5

• r = 0   or     r = 5

• none of the option

Solve

 $3d^2-4d=0$  

• d = 0  or  $d\ =\ -1\frac{1}{3}$  

• d = 0  or  $d=\ 1\frac{\text{1}}{3}$  

•  $d\ =\ 1\frac{1}{3}\ \ \ \ or\ \ \ \ \ d=-1\ \frac{1}{3}$   

• d = 1  or  $d\ =\ -1\frac{1}{3}$  

Solve the following quadratic equation...

x² + 13x + 36= 0

• x = -2

  x = -18

• x = -9

  x = -4

• x = -3

  x = -12

• x = -6

  x = -6

Solve

 $3y^2+7y-6=0$  

•  $y=\frac{2}{3}\ \ \ \ or\ \ \ \ y=-3$  

•  $y\ =\ -\frac{2}{3}\ \ \ \ or\ \ \ y=3$  

• y = 2   or  y = 3

•  $y=\frac{2}{3}\ \ \ \ or\ \ \ \ \ y\ =\ 3$
