Question

solve the polynomial inequality. Express the solution using interval notation.
x(2x+3)<0

Answer 1

this is a parabola facing up, it will be negative between the zeros. the zeros are 0 and
\[\frac{3}{2}\]

Answer 2

so it will be negative over the interval
\[(-\frac{3}{2},0)\]

Answer 3

oops i made a mistake. i wrote the zeros are 0 and
\[\frac{3}{2}\] but is should be
\[-\frac{3}{2}\] and 0

Answer 4

answer is correct though

Answer 5

thank you.. sry it took so long :)
