Question

How would I solve these equations?

Answer 1

51. X = 1/5, -6 (negative six)

52.  X = 0, -3/2

53.  X = 0, 1/5

54. Z = 0, -7/4

Answer 2

51) 5x-1=0 and x+6=0
5x=1, x=1/5 and x=-6
2 solutions x=1/5 and x=-6

52)x(2x+3)=0
2x=0 and 2x+3 =0
x=0   and x=-3/2=-1.5

53) x(5x-1)=0
x=0 and 5x-1=0
x=0 and x=1/5

54) z(4z+7) =0
z=0 and 4z+7=0
z=0 and z= - 7/4 = -1.75
z=0 and z=-1.75
