Question 791359: Please help me!!!!
3x^2 + 2 1/2 x = -2
A x = {-5 +- i[SQRT(71)}/12
Bx = {5 +- i[SQRT(71)]}/12
Cx = {-2 +- i[SQRT(12)]}/7
Dx = {2 +- i[SQRT(17)]}/-7
E x = {-3 +- i[SQRT(17)]}/12
F x = {3 +- i[SQRT(71)]}/-12

15. 11x^2 - 5x = -6
A x = {16 +- i[SQRT(329)}/2
Bx = {5 +- i[SQRT(239)]}/-22
Cx = {-5 +- i[SQRT(55)]}/11
Dx = {-6 +- i[SQRT(11)]}/22
E x = {6 +- i[SQRT(330)]}/-22
F x = {5 +- i [SQRT(239)]}/22

30x^2 + 72x = -54
A x = (5 +- 6i)/-5
Bx = (6 +- 3i)/30
Cx = (5 +- -3i)/6
Dx = (-6 +- 3i)/5
E x = (9 +- 6i)/-5
F x = (-9 +- 3i)/-6
