Question

Solve the equation below. Be sure to list your answers from least to greatest
(-4d - 6) (-4d – 1) = 0

Answer 1

-8d-7=0 i think but not sure i guessed

Answer 2

Answer:

if you mean expansion, we have;

-4d(-4d-1)-6(-4d-1)=0

16d^2+4d+24d+6=0

16d^2+28d+6=0

To find d,we have

-4d-6=0. or -4d-1= 0

-4d=6. or -4d=1

d= -6/4. or d =-1/4

d= -3/2 or -1/4
