Question

Which of the following is the solution set for
x^2 +3x < 10? Express the answer in interval notation.

Answer 1

start with
\[x^2+3x-10<0\] then factor to find the zeros

Answer 2

x<2
x<-5

Answer 3

um no

Answer 4

the zeros are \(-5\) and \(2\) that is correct, but the inequalities are incorrect

Answer 5

\[y=x^2+3x-10\] is a parabola that opens up
it is negative between the zeros and positive outside

Answer 6

so.....
what now???

Answer 7

you want to go with where it is less than zero
that is a synonym for below the \(x\) axis
