Question 1 Question 5 Find the solution. (4D4 - 4D³ - 3D² - 2D + 1)y = 0. Find the solution. (D³ - 3D - 2)y =0; when x =0, y=0, y' = 9. y" = 0. A y = (c,+c_x)e¯*+ (c,+cx)e'/½ (A) y = (-1+ 2x)e¯2*+e2x y = (c,+c,)e¯*+ (c,+cx)e¯/2 B) y = (-2 + 3x)e¯*+2ex y = (-2 + x)e -*+ 2e* D y = (-1+ 2x)e2*+2e=x O y = (c,+cx)e¯½+(c;+cx)e*
