A.x1=0

x2=-4

$x1 = 0 \ x2 = x + 4 = 0 \ x2 = x = - 4$

B.y1=0

y2=2

$y1 = 2y = 0 \ y1 = y = frac{0}{2} = 0 \ \ y2 = 3y - 6 = 0 \ y2 = 3y = 6 \ y2 = y = frac{6}{3} = 2$

C.x1=7

x2=-7

${x}^{2} - 49 = 0 \ {x}^{2} = 49 \ \ x1 = sqrt{49} = 7 \ \ x2 = - sqrt{49} = - 7$

D.x1=9/4

x2=-9/4

$4 {x}^{2} - 81 = 0 \ 4 {x}^{2} = 81 \ \ x1 = 4 x= sqrt{81} \ x1 = 4x = 9 \ x1 = x = frac{9}{4} \ \ x2 = 4x = - sqrt{81} \ x2 = 4x = - 9 \ x2 =x = - frac{9}{4}$
